There isn’t going to be a “perfect” vendor with no potential issues (by issues i mean anything from a slow process to bunk products).
That doesn’t mean that there is anything wrong with the vendors, but some are more sketchy/less reliable than others.
Most likely any of the vendors that has been around for a little while and have some fans, are going to be just fine. But depending on how stressed you would be if things are slow - you might want to opt for ordering from the US warehouses even though it costs a couple $ more.
As long as you understand that ordering from China takes time (some times) and communication might be lacking, you’re good to go.
If you are hesitating simply because you are unable to decide - then I recommend reading more, then DM a member you deem trustable and ask for advice/which out of vendor x,y,z they would pick.
You will most likely receive products, and they are most likely ok as long as you pick from the vendors in here with decent feedback - what you are actually looking for is someone to hold your hand because you are in doubt, no intention to be rude, but there are no guarantees - so no matter how many times you ask, you won’t really have a higher chance of being perfectly safe with your order
