Which is better for vlogging?

The Ace Pro 2. Its flip screen and larger sensor give sharper, brighter selfie footage with less editing. The X4 wins only if you want to reframe a 360 scene later.

Is the Ace Pro 2 worth $250 more?

Yes if you shoot in low light or want the best flat 4K and 8K footage. No if 360 capture is your main goal, since the X4 does that for less.

Which has better battery life?

The Ace Pro 2. It runs about 180 minutes in long-duration mode at 1080p, versus about 135 minutes for the X4 at 5.7K 30fps.

Can both be used underwater without a case?

Yes. Both are rated waterproof to 10 m (33 ft) without a housing. For diving deeper you need a separate case.

Which is easier to edit?

The Ace Pro 2, because flat footage needs little work. The X4 records 360 video that you reframe in the Insta360 app, which is flexible but slower.
