It's a nice bit of kit.

Both have the optical HR (neither of which I think is great in a workout if you're a noodle arm runner like me).

I think the Fenix display is a bit brighter - and definitely more tailorable for watch faces

I feel the garmin is probably slightly more accurate, although looking at the GPS tracks on a map it's a wash.

I like to have different screens for different types of metrics, one for pace & distance, one for HR, one for ascending / descending, one with temp / time of day etc, there's not enough options in the suunto to do this for meThen other extras - the VO2 max calcs, the recovery recommendations

Read DCRainmakers review - it sounds like Suunto isn't putting in the development that garmin is to the software, and just hoping the hardware itself wins people over.
