Should I buy a Fenix 6 or a Suunto?

Hello, should I buy a Garmin Fenix 6 (or 6S) or Suunto Race (or S)? Is Fenix 6 still revealing today?

I regularly run more than 30 kilometers per week, I make treks over several days, sometimes swimming and cycling.

I am very interested in the feature of having a display to follow a GPX trail during a trek or race.

I don’t have a huge budget, maximum 350€. I’ve seen some Fenix 6 at 300€ reconditioned. And I wonder if the best choice is to go with an old model (Garmin) or rather a newer one (Suunto).

Thank you
