I feel for TabNine.
What they're doing is impactful, impressive - and so eclipsed by an unreasonably well-resourced competitor that they don't even get given much credit.
"Not as good as CoPilot" really doesn't say enough about something that's still very impressive.
Personally I thought it was cool but not game-changing, and moved on when I got into CoPilot. I can't comment on the next-gen models.
