We all have our "aesethic" of what we think a "nice looking dog" is. I've never had a bull terrier, but I hear they're amazing in personality.
I love Cairn Terriers....and Westies....but also have never had either of those. We have gotten our animals from rescues---so we have never had purebreds (well....except for a Persian cat we had---that was the ONLY indoor cat we've had. Ever). That cat was wonderful, but I doubt we'll ever have another cat again (besides the ferals that are outside). My husband isn't a fan....and I'm somewhat in agreement with you on the "minions of Satan" belief.
A feral we've had in our yard her whole life--5 years--will not allow me to pet her STILL. She will rub up against my leg and purr....but every once in a while she'll do that and then POUNCE and jump up and scratch with both legs (totally unprovoked--I hadn't even looked at her). I'm afraid to go out my front door for fear that she'll jump out and attack me. This is her (not really a "pet" though---just an animal I've fed for her whole life):
Our actual pet (rat terrier, 14 years old):
