I like big hips and pretty faces, however a plainer head on a more foundation type horse doesn't bother me. Some of these speed bred horses can also look more plain, and in my experience be rough to ride.
I had a Bunny Mackay horse in the 90's I bought for my X. He was plain looking, but sweet as the day is long, loved babys, my daughter was 2 at the time. When she was around him, he would keep his head down to her level, I loved him just for that. The only 2 gaits I could ride him in were at a walk, and a dead run. He could run so fast that at top speed the tears would start to stream out of your eyes and you couldn't see. Anything in between I couldn't ride him, he'd knock your teeth out. He was my X,s first horse so it didn't bother him since he didn't know any better.
This picture here on his pedigree is when I owned him...and yes I loved his pedigree...
