I'd be wary of expecting too much from elsewhere, but what little travel I've done during the pandemic I've been shifting to AF/KL and I've been quietly impressed, especially by AF, although that might be because of how low my opinion of them was! Of course, I live in "The Regions (tm)" so getting to skip the trek down to Heathrow is a benefit. It's much less of a faff to connect at AMS or CDG after than it is to get the train to do that. Flying Blue has a pretty easy route to status too, and they're going double XPs (their version of TPs) until the end of the year.
