I did try some newer kernels a few months ago, but then my wifi stopped working. But this should not be necessary when running a flagship LTS desktop Linux on extremely common hardware from two years ago! I expected more.
No point in doing that. Just use the hardware enablement stack. It gets you the 17.04 kernel/X/etc over the LTS base. Best of both worlds.
But I will reiterate: this is clown shoes. Expecting this kind of effort from desktop users is hostile.
Personally I find all-in-one installers annoying. I find I have to spend a ton of time removing crap I don't want and replacing it with what I do want. It would take me probably as much time or more to install and configure Ubuntu as Arch would.
You might want to check out Fedora too -- I hear the latest release is pretty great. Arch based distributions like Antergos or Manjaro might be good to check out if your only hangup with Arch is the arcane installer.
