Honestly, I would probably say Fallout 2. 1 was great, 3/nv/4 were good to great. But 2 really had something they never managed to replicate.
Beyond that, EU4. But that will be probably eclipsed by EU5 when it comes out. Just so much replay-ability.
Underrail is the best modern equivalent if you want something that plays like Fallout 1/2.
