Demon vs Holley (who do you like best)

I do have a worked over 318 in my volare with an auto trans. I have run a 9000 series carter until the shafts fell apart and then went to a 3310 holley. Granted it is a 750 so naturaly was a little difficult to tune in but once there was great till the shaft seals went out. I did try a 650 dbl pump and it ran better but wasn't as responsive as before with the other holley. I was able to round up a 650 road demon from my father in law that had some problems with the throttle plate being warped. But after a dismantle and a lot of time was able to re-flatten and get to seal and it runs better than ever now.
