I only use Suunto and still using now. Build like a brick hardware wise and battery last very long as the display less colourful and bright. From Suunto core, Suunto ambit 3 and now Suunto 9 baro. All still working but I sold off ambit 3.
However software support is going downhill after company acquired by amersport. But still built in Finland I think.
Garmin I know software support is better and morre mainstream users.
I think if you needs lot of feature, go for Garmin. If only need basic feature and long lasting go Suunto.
