In North America and specifically on TMO, I personally would get a -5, yes. UMTS 1700 is TMO's main 3G/HSPA+ band, so at least until they completely refarm that network to LTE--which won't be for a while--I would keep a -5 over -1.
Plus WiFi calling does not work on the -1. The only Q10 it works on is the -5. Not sure if that's a consideration here, but I thought I'd point it out.
