I can say the UX of Apple Numbers is the best, much above the usability I've found of Excel. Much less powerful, but it is much easier to use Apple Numbers
I think the main bit I love so much about it is having actual tables instead of the Infinite Grid that most spreadsheet software uses. You get named ranges for free, and it makes semantical sense too, among a good number of other benefits (sheet organization, refactoring, simpler styling...).
There are some really nice things that Google Sheets does, and I've done a few fancy things with App Script which isn't too bad, and I do really like QUERY though I wish it was a bit higher power. I just always find myself missing the UX of Numbers, though.
