Every dealer is different and some members will stay with one dealer, others will move around, it's all subjective.
Some members will want quicker delivery because of UK stock, others are happy to wait for Chinese deliveries.
Some dealers have instant, near chat bot responses, others you'll be waiting for a reply.
It's all about what suits you, as you're the one who'll be handing over the money, so you're the one who has to ultimately decide.
Best recommendation is to check out the dealer reviews/feedback and that will give you a sense as to what to expect based on recent interactions. Members will be both positive and negative in their feedback so you'll quickly see the pro' & con's (if any)
There a wealth of information over in the New Members area to digest, especially the below & its be a shame to waste it.

Personally, I'd recommend reading all the stickied threads over there, so you can do all your research, pre, not post, purchase and make an informed decision.
Best of luck
