Gotcha... ok. No. This isn't about which is better than the other, at least not in terms of graphics or anything else. It's about the comparative bugginess of both platforms.
I've played both now and am I the only one who finds the PS4 version to be much less stable?
Stuttering frame rates - way more on the PS4
Freezes/crashes - had four in one evenings play on the PS4, none on the XB1
Loot chest looped animation glitch - Only encountered on PS4
Dreaded connection errors - Encountered one, guess which platform.
Clipping - both platforms, not great.
Distance draw/popping/loading - PS4 was the only place I noticed this happening.
Come on UBI get this stuff together. The PS4 deserves to be treated better than this. Most of my friends are on the PS4 so that's the platform I'll be getting this for, and it should be exactly the same experience as on the XB1, yet somehow it isn't even close. What the hell? This on top of the 1 months delay on content is making me feel very antsy about voting with my wallet.
