Maybe get one set and see how well you like them before you get a second set of the same boots.
I really like the Easyboot Epics. I have to repair gaiters and cables once in a while, but the boot material itself is almost indestructable.
I found Old Macs rather cumbersome and the soles started to crack after just a few rides in the rocks so I sent them back.
I thought the Easyboot Bares were a bear to get on and off.
And I tried the "fit kit" with the Gloves and they didn't seem to match my Mustang's hoof shape so I didn't order the gloves. I think the Epics are the same or similar shape, but because they have the cable tightening system you can get them locked on pretty good even if the shape isn't perfect.
Those are the only ones I have tried.
I was afraid to try the Easyboot Trails because they look like Old Macs, but maybe they if they are the same material as they Easyboots they are fine. Easycare makes all of the boots you mentioned (except Cavallos) so I don't know if the materials are the same or not. I have not heard of anyone else having the old Macs cracking though, so maybe I just got a bad set. But at the price of the Old Macs, they should be wayyyy more durable than that. Epics are harder to kill, for me anyway.
I think boots are kind of like saddles in that everyone has a preference of features they like and dislike and some work better for some people/horses than others. I don't think there is a right or wrong answer, just finding the boots with the features that work the best for you. That's why I said try one set before you buy two sets, just in case you say "boot xyz is a bear, maybe I will try boot y."
