Which slot provider do you avoid completely?

There are a few providers I mostly skip now, even if the artwork looks good. After a few sessions on different games, I keep seeing the same setup: the base game can go 80 or 100 spins with hardly anything, then the bonus comes in and pays around 8x or 12x. I’ve had a couple of sessions where I put 300 or 400 spins into a game and the bonus barely made back what I’d spent getting there. I can deal with high volatility, but I don’t like games that show lots of near-misses and little line hits, then make the feature look more exciting than it plays. A lot of the catalog starts to seem like the same game with different symbols. The other thing that puts me off is choppy animation. If the screen is running at what looks like 12 frames per second, it gets annoying pretty fast. Does anyone have a provider you’ve stopped playing altogether after trying a bunch of their games and getting the same results? Would you keep one or two titles from them in rotation, or just move on? thanks
