It's not really a question that can be answered.

Lots of Alibaba/Aliexpress resellers are specialised resellers who only stock a handful of brands. They're not online stores selling everything.

I buy most of my stuff off Aliexpress. I don't have favourite stores but nothing I ever bought has disappointed me, except for a Pipo mini-pc.

I will usually avoid the cheapest few stores for anything unless they look like they specialize in it.

I avoid new sellers that have a couple of dozern on their rating thing but 1000s of things listed

I avoid ones that have their listings in a mess and most of the listing is copypasta crap about how they sell things and please dont make dispute and then a huge list of other things they sell because that annoys me to scroll thru.

Most of all the thing I find annoying on there is those keyword loaded spammy NFC ring listings that seem to come up for anything you search for.
