767 is the staggered configuration with the foothole cubbies like you'll find on DL and others. CIP didn't include IFE so you'll get a Samsung tablet that will be collected prior to landing
A330 is legacy US envoy seats- they were one of the first reverse herringbone products. The seats are a little bit older than some of the other AA installations but I think are hands down better - more private, more storage space, built in IFE, no coffin like cubby hole, etc
Service will be hit or miss either way. I'd go A330
