Whatever you and your horse are most comfortable in is the best.
A saddle with a high(er) cantle will hold the rider in place in the event of a quick turn, but might not be the best bet if riding a bucking bronco as it would hold in the rider when they most needed to bail out.
A higher cantle, and pommel, makes it easier to stay in the saddle while going uphill or downhill.
A saddle with a low(er) cantle is easier for bailing out in the event of an emergency, but won’t hold in the rider as well for those quick turns.
Endurance saddles are made usually with close contact on either an English or western style tree, with or without a horn, but of paramount importance: they are designed to be comfortable for both horse and rider for l-o-n-g rides.
I <3 my western style endurance saddle (it weighs 17 lbs.). Bought it used for $250 because I needed something right away to fit my horse, figured I’d replace it as soon as I found something I liked better. Fifteen years later (and a couple of saddles later) I have never replaced it because I’ve not found anything I like more than that saddle. It’s not impressive in any way–no one ever compliments me on my pretty saddle–but I can ride all day and am ready for more afterwards.
