Bubsy II — my least favorite of the series — has the mid MD/Gen and SNES versions and the absolutely abominable Game Boy version. All seem to work fine but I admit that I cannot enjoy the baffling controls of this game. The GB version controls especially poorly and slowly.
Bubsy in Fractured Furry Tales — the only game in the collection I've never played before — kinda sucks. I appreciate the fact that it feels more like an alternate universe Bubsy 1 but the enemy placement is even worse. Can't comment on the Jaguar emulation, but it played decently.
Bubsy 3D Refurbished does not make the infamous original game particularly playable. If anything it's slightly more annoying, though that's not the fault of the devs, whether at Bend Studio or Limited Run. Bend Studio didn't know how to invent the 3D platformer, and LRG just took what they had.
The hotboxes on the Woolies are still comically large, Bubsy's deceleration is still ridiculously slow, and the game still feels like it's a mess. The controls are a bit more comprehensible and Bubsy can go much faster without having to come to a stop to change direction.
Bubsy 3D, like most Bubsy games, is a theoretically very fast 3D platformer that doesn't actually give you an outlet for your speed because it punishes you for going too fast. The new controls make this more obvious than it was in the original game.
I'm a bit bummed that there doesn't appear to be an option to render Bubsy 3D at native resolution, so it still runs in its native resolution with widescreen expansion. It's a game that's got a peculiar but interesting art style and it'd be cool to flaunt it better.
The widescreen implementation is clumsy and has terrible clipping issues in the area outside the 4:3 region. I almost wish they didn't even bother with widescreen if they couldn't implement proper FOV fixes.
Overall, though, Purrfect Collection is a solid collection of old Bubsy games and $20 seems like a fair price for what's on offer if you actually like Bubsy. It does replace the $5 Bubsy Two-Fur, but is a more competent collection than that with double the games.
