Opinion time:

Volo race are pants. I've seen more broken pairs than intact.
Reaction pros have a bad habit of dying unfortunate deaths, at least when used by underwater hockey players. They bend in the middle, rather than flex progressively. Mind you, our goalie swears by them. I swear at them.

Mares quattros are a LOT better than either, but are quite tiring to kick for what they are. The avanti excels and superchannels are cheaper and softer, but don't have the same drive, it depends on how much you weigh and how deep you want to go. Jeez, I sound like a Mares advert!

The other options are all full freediving/spearfishing fins. They're worth it if you get into it, but if you change your mind, its more money down the tubes. At least with the others you can sell to underwater hockey players!
