Well, that's less about how long the Maximals/Predacons live and more about how the Autobots/Decepticons entered the realm of myth and legend in a mere 300 years.
I've finished the first 2/3rds of the series and it was about like I expected. "Disappointment" is too strong of a word -- I watched the tfcog dubs years ago (they reached ep. 10 or so?), so I knew the gist of the early episodes was "Find the thing!" Part 2's new toy of the week section is entertaining. As a fan of Uprising, I was surprised and pleased to see Crazybolt and Bazooka were introduced together. For some reason, I had a belief that Bazooka, Killer Punch and Hardhead were regular cast members later on, and that Survive led a team that included Sharpedge, Randy, and Bump. Maybe that happens in the final third, but it was good to learn otherwise.
Neo suffers from the general problem of having a small group of characters defined by a single trait each. Original BW could be a small group because there was some depth to their interactions with each other, and even some character growth. Original G1 worked with one-note characters because there was a large enough group that they swapped out each episode, and it didn't feel repetitive. "Microbots" had the rough and physical Brawn learning to respect the skills of the studious Perceptor, which was cool...but six episodes in a row of those two playing off each other in the same manner would have become dull.
The Neo Maximals are growing together as a team as time passes, which is worth mentioning, but their individual personalities are suffering as a result. As Break learns to be less impulsive and Stampy less cowardly, they're losing the only defining traits they really had. And because of the language barrier (for me at least) it gets harder to tell them apart, especially when the animation isn't showing on -screen who's speaking. I just finished the second clip show, and I really had to pay attention to understand whether the clips were talking or if it was a voiceover from Heinrad or somebody else, because I can't recognize most of their individual voices.
Still, it has been a great experience, and I'm glad to finally fill this hole in my Transformers experience.
