What suits one person will not suit another or may not suit the horse, the best advice is to find a saddler who will bring out a selection for you to try, don't use one that can only supply one brand, ideally get someone who will have used as well as new ones so you can get a feel for what you like as well as find something that fits the horse as it really is individual preference especially if you want to jump as well as do flatwork in it.
Make sure you get a proper chance to ride and jump in one before making a purchase.
I agree with Be Positive too.
However, I love my Jeffries Falcon F1 and before that I found the Black Country saddles very comfortable. But everything will depend on your horse, your length of legs, size of bum etc etc.
Not a fan of any of them to be honest. I know more horses that have problems with the likes of wintec/thorowgood than any other saddle and its mostly because people assume you only need it to fit the wither. Saddles need to fit the entire horse, and owner.
I use a kieffer, its what my horse chose to be honest. I love it too, and i'm very comfortable in it. Its also adjustable (within reason and by saddler only) but im not sure if it would be good for eventing cause it can be quite deep and high at the back - but im sure there are other versions etc thats just how i find mine..but my biggest jump ever has been 60cm lol
I love my Kieffer Garmisch. Done everything in it from XC to dressage. Only one my horse has ever got on with even my made to measure dressage saddle which I gave up to return to my Kieffer which Ive used for about 12 years.
