Where do we start about the Dreamliner?
By now, the problems have been well publicised. Perhaps the practices at Boeing for the 737MAX8 were inherent with the B787. Every airline chooses its own interior fittings but some are showing signs of wear already. Perhaps it's the numbers of bums on seats that's making the TUI ones look tatty.
Personally, I like Airbus. Know it's girly but looks nicer and the A380, wow! Another iconic aircraft that hasn't been utilised properly by some of its operators. Even US carriers have moved away from Boeing, much to their disgust.
My top 3 are A380, Concorde and VC10.
