After this isekai update, Force Shields are superceded by Tower Shields, Kite Shields of Barrier, and Tower Shields of Barrier in the amount of block provided, by a large margin.
QUOTE(BlueWaterSplash @ two weeks ago)

After some thought, I think Force Shields may still be roughly balanced with Tower Shields. Even Tower Shields of Barrier and Kite Shields of Barrier. (Perhaps none of those are the best shield, and it is a dark horse).
It surely doesn't look like it, but they are. (Hint) Tenboro has already explained the reasons here and there, in parts. The question is whether or not you believe (as it's not easy to understand why). If I get unlazy enough, I may explain it in the HV Research Thread (there are important related old discussions there).
I've spent a long time thinking about this and the balance of styles and I think my overall conceptual understanding has improved. The following analysis is largely for Persistent or version independent, yet is useful to post here.
Myth - 1H has the strongest defense/survivabilityStandard DW Light with Rapier/Wakizashi, or better yet 2x Wakizashi of Nimble, is a contender for strongest defense/survivability. Isekai made us forget, because it doesn't seem like it once beyond beginner Tower. DW Light was my original Persistent style prior to level 250, and was often my isekai style at that range. DW offers among the strongest defense at low level, until utterly overtaken by 1H around level 200. This is because that is when 1H counter attacks quickly start to work better, and they roughly improve 1H defenses by a factor of
4x as that is the length of Stuns inflicted on all the monsters.
However, that 4x ability doesn't scale up. By level 260 all the special powers that 1H gets, both on defense and offense, are done evolving. While all styles' general defense and avoidance stats continue to improve, due to level and more importantly equipment quality.
Once fully forged and Peerless at level 500, I suspect DW Light with Rapier/Wakizashi may once again have comparable survivability to 1H. There is a very difficult analysis for this which I'll leave for HV Research in the future. The tl;dr math is that once you have high enough Parry above 90%, that eats into the meaningfulness of Stunned monsters doing nothing. As parry/block/evade approach 100%, the 4x factor exclusive to 1H
shrinks down to 1x due to your raw ability to defend yourself without needing the help of stuns.
DW Light with Club/Wakizashi and spread targeting is another contender for top survivability. We've never fully experienced the full survival potential of DW in isekai because I don't think anyone ever got strong enough. How high you go in Tower matters not; it's
your Peerless quality that matters to grab the title back from 1H.
Corollary - Force Shields improve relative to Tower Shields when you are strongerThe relative stats of Force versus Tower Shields do not shift as you increase in level or forging. This new Corollary is only in addition to my previous statement that Force and Tower are actually
roughly balanced and many players didn't realize it yet.
The tl;dr no math reason why Force and Tower are balanced...if
Basara Nekki were to re-do his Persistent defense tests of 1H Shadow Veil in the HV Research thread, where a shockingly pitiful result was revealed, the result will be completely different in the isekai. Note that Shadow Veil was intentionally split into two effects. For the purpose of defense, the new Evade +20% component should perform identically to true evade, while the +20% Shadow component has the almost-nothing 1H effect of before.
Since Force Shields have low burden, depending on your stats and armor,
you can get a lot more Evade, which is almost the same as Block
after the update. That is why Force Shields are still competitive with Tower Shields.
Now the new Corollary which, after years, I only finally understood today. If you have a very low, say 1% block, then your measured actual damage reduction with script should be 4%. This is because of the 4x special 1H multiplier mentioned above. If you block even 1 time, it is worth 4 blocks because of the Stun. However, once you start to get a lot of block, say 60%, you obviously cannot have more than a 100% damage reduction. As the
Myth explained, the 4x survival multiplier of 1H gradually shrinks to 1x, as you approach becoming a perfect being.
Therefore the stronger you are, fully forged and Peerless at level 500, a Force Shield's performance should improve slightly more than a Tower Shield. When you are near perfect, the new and improved Evade will perform exactly the same as Block, for defense purposes only. Before you get perfect, 1H Block will still be a little better than Evade point-for-point, but by a moderate factor like maybe 1~2x.
QUOTE(Tenboro)

- Parry and Resist for monsters now use a logarithmic function above 50%, starting from 2x resist/parry compared to accuracy. At 3x they will have ~57%, and in practice they should never reach the 75% cap, as it would take 13x more intercept than accuracy.
I guess many of us forgot how much parry a strong DW user gets. According to my calculations, in Persistent at level 500 an offhand Peerless Wakizashi of the Nimble provides 77% parry stat alone, and a peerless DW Rapier/Waki user would have over
94% parry (dexterity increase partially omitted). Dual Peerless Wakizashi of Nimble may have over
96.5% parry (dexterity calculation included).
Since monsters are different from us now anyway, maybe we ought to uncap the new parry formula after all, otherwise we are severely limiting DW defenses on the ultimate players. If the parry cap was increased from 75% to 99% when parry is 3x --> 4x more than accuracy, the linear scale would remain the same as before.
