Garmin Instinct 2 standard with third party surf app or Instinct 2 surf edition?

Hello,

I am considering to buy a Garmin Instinct 2 to use it for different outdoor sports and crossfit workouts.

I want to use it for:

- surfing 

- crossfit

- camping and hiking

- mountainbiking

I find it important to have good surf options like tide forecast, surftracking. But i read a lot of bad reviews about Garmin own surftracking on the Instinct 2 Surf edition. I also read good review about the third party connect IQ app SurfTracker 2.

So I was wondering what is the real difference between the Instinct 2 standard edition or the Instinct 2 Surf edition is?  Is it worth the extra money or should I just buy the standard version and download the SurfTracker 2 app and a Tide forecast app in the Connect IQ store?

Thanks in advance!
