Best Boots for Strap fins?

Hey everyone,
I'm looking at upgrading to a pair of Atomic Aquatics split fins (strap, not full-foot)
and was wondering what would be the best kind of dive boot to use with them?
A full hard-sole boot? or a semi-hard sole boot?

The two i'm looking at are:
The atlantis legacy b20:
(a full hard-sole boot)

and the atlantis quest b10:
(a white-soled boot more suitable for boat diving apparently)
What do you guys think would be the most optimal, best for propulsion etc?
Thanks a lot.

I say go with whichever one fits better for your diving needs. The soles on my boots only play a part when I'm walking to and from the dive site or when I'm walking around on the boat. They don't really matter once I put my fins on.
