I don't think you'll be satisfied until you try it yourself.

The issue here is that you have been asking a group of players who have been there/done that with SCH and WHM since 2.x to model essentially the same pairings with AST Sects.

With AST you are getting the same core abilities regardless of Sect, so the only really relevant question is "regen or shields?" The sect bonuses aren't nearly impactful enough to be a factor.

Anyway, I recommend that you try this yourself so that you can make whatever observations you wanted to make.
