In 2017 my dad and I both bought brand new G4 165s. I bought a 3” and he bought a 2.5”. His reasoning for the smaller track was that he wanted to use it for riding around the farm too and the smaller lug is better for that. In 2018 my dad snowchecked a new sled with a 3” after seeing how much better the 3” is in deep snow.
We jumped back and fourth many times and the 3” track is hands down more fun to ride and more playful than the 2.5”. The 2.5 can pretty much get to any of the same places as the 3 but you have to be more on the throttle and really work the sled more in deep snow. The 3 gives you more time to think and more forgiveness if you really need to get out of a sketchy spot. I rode the 2.5 and 3 in almost any snow condition and as long as you have a few inches of fresh or decently soft spring snow the 3” is nicer to ride.
Unless you want to ride trails without using scratchers or ride hard packed around the cabin I wouldn’t buy a 165 3”(for riding BC). Apparently in the 154 its a different story but I don’t have experience with that. The 3” is definitely less durable than the 2.5 though
