I've tried all couriers available on taobao. And I am most impressed with 4px. If you notice 4px's rate is the most expensive, but I got my shipments in like 6 or 7 days. That's heavenly, just like shopping from Malaysia.

I don't know why people say 4px partner is abx as all my 4px parcels use airpak. Which is good. What I like the most about 4px is it sends me SMS notification whenever my item arrives at the warehouse in China and when my item is our for delivery.
DEX is good too. Its local partner is GDEX, which is very efficient. But the lack of SMS notification and it typically takes 9 to 10 days.
All in all, sometimes I think it depends on your luck as well. My tips is to never buy so many things at once. Customs won't have the time to check everything, but when your package is big or heavy, it stands out, and more likely to be inspected, hence detained.
I do agree with you on 4PX being very good, until recently. Maybe it's due to the overload of shipment from the 11.11 and 12.12 sale? Let's see if it get improves.
My experience with them has been consistently receiving my parcel on the 4th business day after payment. Eg:
Day 1 - payment and ship out
Day Day - receive.
Best was once I receive on Day 3.
But recent parcel was like Day 6, then the last 2 was like 2 weeks.
