Breed preference depends so much on gingival horse. Like Arabs for their natural beauty, admire mustangs for hardiness. I like stock horse breeds best, and more than likely, I'll find a mustang more readily with a stock horse build.

Welcome to HC, many good places to check out. Be sure to checkout some of Grouchy Grizzly’s thread. Many nice pictures to look at. Best Wishes.
They are each very special. I also have an appaloosa. Come spring, a papered to the hilt Quarter Horse will be joining the crew.
I grew up on the back of a POA/Arab. He was awesome.
I don't like breed bias, and I have heard plenty of it.
My apply mare will go from dawn till dusk and then some, if you ask her. She has stamina and courage to no end. She's the most honest, hard-working horse I have ever had the pleasure of knowing.
My Arab is the best kids' horse out there. She's not spooky, nervous, or high-strung. She's just----wonderful.
My mustang has given me quite a challenge at times. She's a strong personality. At 4 and a half, she is settling down and becoming a good trail horse. I think we'll do just fine!
My soon to join us QH gelding--I'll have to let you know about that one later. He is ready to get started with groundwork in the spring. I am hoping he is sensible and steady!
I'm partial to both breeds. I own a mustang, and board her at a small Arab breeding/training facility - every day I go to the barn I get to immerse myself in the best of both worlds. But while I admire Arabians for their intelligence and beauty, I really only ever want to own mustangs. There's just something about a feral horse that gets me! Plus most of them make excellent all-round mounts. My mare can do anything!
If you were looking to buy a horse I wouldn't limit yourself to a particular breed.
