Is there any reason you'll use Aliexpress and not eBay? For things like this they are often the same sellers on both sites. I think your odds of getting something counterfeit are about the same
Many sellers on eBay do paypal only, and after dealing with paypal's horrid customer service, I'll never use it again.
All AliExpress orders are escrow, so the seller doesn't get their money until the order is confirmed received. While the AliExpress dispute resolution is poor, I use a credit card for all purchases and will do a merchant chargeback if I don't get a refund through AliExpress.
