Hey guys, so I got done fully ampying Lycoris Miko a while ago and now almost have 100 of each ampy to max a second six star. I'm choosing between:

Colchicum
Kugaisou
Sakura

Is there any one of them that is particularly strong overall, or are they all pretty much comparable? Synergy with my other six stars isn't important right now, I don't have that much of them.
