Just because you are doing hunters doesn't mean the the jumps are going to be small. You can jump at least 4 foot still doing hunters or equitation.
I think you would prefer jumpers if you like doing a fast course, like tighter turns and enjoy much more complicated courses.
You would like hunters more if you like a slow, controlled course that looks effortless. IMHO a good hunter course looks kind of boring because the horse and rider make it look so easy.
My favorite part about jumpers is that it's you against the time/faults. There is a judge but in general they don't effect the score too much. You can have a horse that doesn't move well, cheap tack and inexpensive clothing and you can still win the class. I really hate the politics of hunters. That said, if I could have 2 horses to show, I would ride one of each =) they both have their good points.
You sound like you'd prefer hunters, just the bigger classes.
