They're really only worse in the sense that they can be louder. In a datacenter/mining rig/etc where you don't care about noise at all, they're pretty much the best solution to cooling a large amount of cards as they blow air out near the outputs instead back into the rack.

what is the appeal of blower-style cooling?, i always heard about it being worse for cooling

Thanks – and what is the quieter solution vs. blowers? Liquid?

Most mainstream solutions will be quieter than a blower at full tilt (i.e. the normal GPU design on having fans on the face that blow air back into the case). That said, blowers aren't inherently stupidly loud or anything. I've got a reference model blower 5700XT and have the fan curve set that I can't ever hear it with my (open back) headphones on and never really go above 80C. If I said fuck it I could turn the fan curve up and have it sound like an original Xbox 360, but my temps sure would drop!

Oh, simply having a fan does not a blower make then!

The quietest solution is passive but you won’t get very good performance out of that.
It’s all a balance

Passive would be like a heat sink?

The liquid system really just helps move the heat to a new place in your rig. To get rid of it, in general the bigger the fan the more air it can displace at a lower speed, which in turn means less noise.
A good liquid system which moves the heat to a radiator at the top/front/back (depending on where your have clearance) of your case and big fan or fans to push it out would probably work best

Blower fans are better if you want a bunch of cards in one system. Open air coolers dump too much of the hot air back into the case and are usually thicker. For non-gaming loads it’s frequently better to have more cards at less than max speed.
