Spent the last couple of weeks trying a few different places for slots and yeah... some are miles better than others once you get past the signup fluff.
For me the good ones are the sites that just work without stuffing around. Games load quick on mobile, the lobby isn't a total dog's breakfast, and there's actually a decent mix instead of the same 20 reskinned games chucked in your face. If I see heaps of providers and I can jump from old school stuff to the newer volatile ones without digging through five menus, I'm already more keen.
The other big thing is how it feels when you're actually playing for a while. Some sites seem fine at first, then the game freezes mid-feature or boots you back to the lobby... proper mood killer. A couple I tried were smooth as all arvo, no worries. That's the stuff that makes me go back way more than some flashy promo banner.
Also reckon fast cashouts matter way more than people admit. I can live with an average bonus, but if withdrawals are slow or support goes missing the second you ask a question, I'm out. Same if the wagering terms are a bloody maze.
Game-wise I've ended up liking the sites that have a bit of everything — not just the usual Pragmatic overload. Give me some NetEnt classics, a few Play'n GO bangers, maybe some weird ones from smaller studios too. Makes it feel less copy-paste.
Curious what everyone else rates when picking a slot site. Is it more about the game library, smoother mobile play, decent promos, quick payouts... or something else? Chuck your favourites in, or the ones you'd avoid so the rest of us don't waste a deposit on rubbish.
