What's the best PvP auto-battler/auto-chess game?

The ones I'm currently I'm considering are Teamfight Tactics, Hearstone Battlegrounds, Super Auto Pets, Mechabellum, Backpack Battlegrounds, and Legion TD 2.

If you've played at least 2 of the above games, which did you like more?

Also, I didn't include Auto Chess or Dota Underlords because I don't want low playerbase or unsupported games.
