Best Channel(s) in '915' MHz band?

I’m wondering if there are channels in the 915 MHz band that are better (quieter) than others? I imagine that avoiding channels that overlap RFID interrogator bands is a good start but I’ve limited knowledge of other areas of the band that might be troublesome?

The ‘Best Channel’ is really going to depend on your particular area, it might vary by location or country.

Get a cheap SDR and scan the band.
