Again, we'll have to see. The show is buzzy and high-profile for an Off-Broadway musical, but on paper it doesn't seem all that commercially viable. You say it'll probably transfer unless it's a fiasco, but I'd be more inclined to guess the reverse:
It probably won't transfer unless it's amazing (or rather, extremely well-received). And there's a lot of middle-ground between fiasco and amazing.
Plus, for all we know the show might be mediocre, but will still feature an incredible, must-see performance on par with Kalukango.
For the record, I have nothing against Paradise Square - I haven't seen it. And I have no vested in interest in Suffs. I guess I'm just trying to make a point that it's hard to crowdsource recommendations between two shows, when one of them is a total wild card.
My recommendation to the OP would be to go read up on the Paradise Square reviews/threads, listen to clips of the music, etc. Then read the description for Suffs and listen to some of Shaina Taub's past work. And just see which one you think you'll vibe with more.
AND/OR - depending on when your trip is, wait until mid-to-late March to decide, so that you can read early reactions to Suffs.
