mio 315 or 305 hc rather than garmin 810?
Have been looking What garmin to get and suddenly came across these mio options:
The maps look clearer and even better data available while riding (e.g. distance to and gradient of next climb)
Can't really see a reason, apart from their large size!, to get an 800 or 810 instead of this. Garmin make me choose between a"surprise me"-type option (present on the garmin edge touring but not on the 810) and cadence (on 810 but not on touring). Mio has both.
Am I missing something obvious here or is this just a petty schoolyard "garmin's what the cool kids use "thing?
Any help or advice gratefully received!
