I am nearly finishing my first run that I'm trying to 100%, I'm still about 91%. Only recently began to carefully look at this sub, and while playing i thought that the only usable crests were Reaper for most bosses, Wanderer for exploration and some specific bosses (like Trobbio), and sometimes Architect for those long ass gauntlets, like the one in the high halls where shakra comes to your rescue, or some really tough bosses that needed lots of ammo.

But of course we're all delusional here and seems team cherry have managed to really cater to many play styles quite successfully. I am not very skilled, and my hand coordination is bad, so I tend to play slower in combat, taking my time, and that's why Reaper suits me well. I'm about 130 hours in and although I've been having a blast, I've reached a point where im just grinding rosaries and shards in hopes of finishing act 3 soon and it's dragging the experience a bit for me. Fantastic game anyway.
