I bitbaked gumstix-xfce-image from scratch on AWS EC2 x-large instance (8 threads, 8GB ram). 

Here is what I found:

RPM: 
real 251m54.934s
user 749m7.409s
sys 516m18.156s

OPKG:
real 209m50.643s
user 664m48.869s
sys 484m27.513s

DEB:
real 226m57.561s
user 682m2.461s
sys 482m59.031s

So yes, like Trevor said, OPKG has the fastest build time at 209 minutes, versus DEB's 226 minutes and RPM's 251 minutes. This alone probably isn't enough reason to use OPKG again. I think package integrity, like Ash mentioned, is important.

Interesting. Sounds like it is time for an experiment ;-).
