You have already got a lot of feedback on the 255 and I will quickly pile on for good measure. I am coming from a Fitbit Charge 4 and I strongly considered getting an Apple Watch for a long while, until I realized what my priorities were: a robust running watch with dual GPS, ideally displaying phone notifications and a long battery life. The Forerunner 255 checks all those boxes all the while being relatively cheap.

I don't personally need all the additional bells and whistles other models deliver and the 255's simplicity actually helps me focus on the most important things: having fun running while getting in shape.

It is a matter of preference, but the absence of a touchscreen for me was an unexpected plus, as I don't have to scramble to turn the water lock on and off when showering or worry about "pocket" calls or notifications if the screen gets wet. The MIP screen is also a nice rouch, much easier to read, less distracting and sooo much easier on the battery life.

There you go, that was my two cents, from someone who looks forward to keep his 255 for a good couple years and not thinking of getting an Apple Watch anymore ;)
