why are some slot developers known for tighter games than others

i’ve been messing with a few of the newer slots lately and gotta say, some of these so-called “top” developers make games that just eat your balance way faster. i get that variance matters, but it feels like some are built to just never give you a break. i don’t expect to win every session, but when you play for an hour and barely see a bonus or anything decent, makes me wonder if certain companies are just known for being tighter. anyone else notice specific developers with way less frequent payouts?
