Do many medium to large companies use mid-range to high-end SonicWall firewalls?

I just wanted to get some insight here as I have very limited corporate IT exposure and experience. I'm sure its common for small businesses to use a SonicWall TZ or something, but is it common that medium and larger companies use the mid to high end SonicWalls at all? I'm just trying to get an idea of market share with regards to the bigger firewalls. I assume its mostly stuff like Cisco, HP and PA.
