I'd go with ALPs as they are updated frequently, and also have a hardware advantage with more sensors per head, etc. You'll pay a bit more, but worth it in the long run. I'm not familiar with Premier in Fremont. Not all installers are the same. Just make sure they place the heads where you tell them to (with help from everyone here) and make sure they are level/square on all axis. Also, chime back here after the install with photos, etc. Send me a PM if you want to get tested.
