My list:

Shantien phase 4, Dhisufiroa phase 2, Mi Ru, DIorekkusu, C. Fatalis phase 2

These are also some of my favorite monsters, which might be a coincidence or it might not, but these are all amazing themes. TBH I can't even imagine a bad Monster Hunter theme, only one that gets boring from being overplayed (like Gen 3's D. Isle/Lagiacrus theme) or ones that don't really work with a battle scene (looking at you, Zerureusu phase 1). I mean, it's a good theme for meditating or going to sleep, but it doesn't really work for a celestially powered Rathalos who could kill you with lasers the second you let your guard down. That's the closest I can come to a least favorite.

I can't think of any you left out.

I think Frontier's soundtrack is much better than the main series themes. Monster Hunter X themes like Dinovaldo and Tamamitsune are the closest the main series has come.
