Fast courriers (DHL, EMS, Fedex) from China and duties. What is way to go?

I mostly use epackage or standard and never paid duty. It takes 14 days to 40 days however. For a fast option, I used DHL once and it was horrible. Brokerage fees were super high. Customer service was the worst to say the least.. But maybe I was unlucky.

• If you need and fast option, which carrier do you find the best?
• Is there a way to pay duties in advance with some of them? Would you consider it a good option?
