Percentile roll under
3d6 roll under
After that a fair number that are fine
Near the bottom is dice pools, I just don't particularly enjoy them
At the bottom is games with dicepools and fistfulls of dice, if the game has you rolling a dozen d6 or 30d6 or frankly anything much over at the very maximum five or six dice in one go then it actively detracts from my enjoyment.
It's a core reason why I dislike many indie games, nothing to do with shared narration or Forge theory or any of that stuff, it's just that many of them are dicepool systems and a fair few are about rolling loads of dice because a lot of those guys really seem to like rolling dice. Leaves me cold every time.
For me a dice system should be simple, intuitive and quick to read. I should be able, as player or GM, to look at my abilities, look at what I'm trying to do and have a fair idea of what my odds are. Dice pools make that harder, percentile roll under makes it laughably easy.
