Aren't really any benefits .. other than getting the generation chip next to your name. Each generation you'll acquire xp faster and faster with the xp bonuses inherent to the generation but that simply makes it less painful to level up and unlock everything again.
After the first gen where there are no generation requirements, the generation requirements will show up at the bottom of your Challenges once you unlock Challenges (lvl 4?).
Thanks for the info Kuj...I doubt I'll ever get to 10 but will have fun with it regardless.
Sorry for hijacking thread!
Now about those plasma railguns...
