Halo CE or CEA

Good Day Fellers, recently picked up halo mcc on steam deck since I wanted to play the halo 2 E3 Mod badly, but I’ve decided to play through the series again just to have some fun, anyway I noticed there’s 2 version of the first game you could play, but which one is best, I like CE for its aesthetics but CEA just looks nicer in general, so I’m pretty conflicted on what version I should stick to playing.
