Superman and Wonder Woman are both pretty good. Batman's regular is okay, not a fan of the tactical suit. I don't like the suits for Aquaman, Cyborg, or Flash.
This is pretty much exactly exactly where I fall as well. I once saw someone say Cyborg looked like an LED light in some crumpled tin foil, and that's honestly what he looks like with all the folds and angles.
Ironically, I think this Flash figure here actually looks way better than the actual onscreen Flash. Something about the costume looks better as a toy than it did in live-action, IMO.
