SubCM Chandy is pretty great from what I've seen, although I haven't run it myself. I do use Pursuit Mega-Aero fairly regularly, so there's that. It's especially nice on teams that have Chandy problems, like anything involving Lucario.
I've been using Sash Espy on a Beedrill team, originally to get replays for my last submission, but I really kind of love it. Especially now that Klefki is back in and does so much better with Espy's other main niche, dual screens, I think it's my favorite set for her right now. Once replays are back up I'll have to post some.
