Bitpay or Coinbase?

[jacktheking]

Which do you prefer when buying things from merchants which accept both Bitpay and Coinbase. I just bought another $10 Amazon Giftcard from Gyft.
Gyft asked me which Bitcoin processing do I want to use - Bitpay or Coinbase. And since Coinbase have a lower rate (0.00001 lesser than Bitpay), I choose Coinbase. However, it require me to sign up.. etc.. So I close the tab and switched to Bitpay.

In short, I choose Bitpay (even if it have higher rate) because it is simple.
