I was almost always on battletoads until the exp from the half-hourly battles stopped levelling me up, now I play on IWBTH for everything except arenas and item worlds.

Normal for things to go through quickly like Arena, currently Nintendo for half-hourly battles but will change to Battletoads once I stop getting enough exp to level. Nightmare for Grinding.
Hard for blowing through arenas and item worlds (to give myself the off chance of shard drops), IWBTH for random encounters, and I'll probably use Battletoads when I start using grindfest again for crystals.
Just started to use battletoads for random encounters was using Nintendo previously. Just use normal for arena to clear faster and currently using hard for item world to level my next weapon.
