I prefer Clinton, mostly because I've seen Parelli followers try and befriend their horses with bribery or coddling that results in being trampled by their horse or crowding them. I recall a situation where we had the grain bucket race and there were two individuals that I knew followed the Parelli circle... Their horses about clobbered them for a bucket of grain.
I like that Clinton is a bit firmer (sometimes to a fault) and I've liked his methods. However, that being said I stay away from any horses that have "natural horsemanship" tied into their sale ads. More often than not they're a part-time natural horsemanship "trainer" with a horse that has no respect.
Then again anyone trying to be a "friend" with a thousand pound animal is asking to be walked all over.
I've done things Clinton has done, but I don't follow him "religiously" I prefer John Lyons ;)
