What are your Opinion/Experiences with the Strixhaven Elder Dragons?

I want to build one of them but I still haven't decided which one. So I would like to know your opinion about them or experiences playing with them, why you picked them, some fun interactions/moments, etc.

For what I have seen/heard Witherbloom is the strongest but can be too straight forward (boring), Prismari is just too expensive and a threat to be let alive, Silverquill is good, Lorehold is quite interesting but being boros is a drawback imo and Quandrix is good too.
