Anyone got any experience/strong opinions about choosing between these two for fell running?

Thanks 

I haven't used the garmin but the sunnto takes ages to find a GPS signal. When it does find it though it does not lose it 😁

That's my only gripe about it otherwise its a brilliant watch 

Thats funny, Ive had the opposite problem between the two brands, a Garmin takes foreveerrrrr to lock on GPS - but my Suunto Trainer locks on almost immediately... hence me leaning towards Suunto.

The Suunto app side is not as powerful as Garmins 'Connect' app however I feel that the Suunto UX on the watch is slightly better and more intuitive.

I would say that if you want to compare them, its like Apple (Suunto) and Android (Garmin).. make of that what you will!
