I like my horses on the speedy side.
When I touch with my heel, they had better be moving.
My mare right now is perfect. I don't have to kick to go, or squeeze for that matter, just a cluck and a little shift in my seat and we pick up a gear.
She does get a little fired up, but I have no problem controlling her (light rein, soft leg cues) when she get's hot, and I ride her in a plain snaffle. I love it when I can let her stretch out a bit into a hand gallop and bring her right back down with minimal effort. I don't like having to force a horse to stretch out.
I'm blessed with 2, probably 3, mares that have a ton of forward, but are never out of control.
I have issues with horses with no desire to go. We don't get along.
