Keeping the same kernel running for long periods can leave you exposed to security vulnerabilities. Either stable or LTS kernels will be similarly exposed, if their latest backported versions are not booted with. I appreciate you're not running a public server so your profile is not as much at risk, but bad code in some application which hasn't been patched up could still leave you exposed. > I have even built a kernel but never actually booted it.

Besides any booting errors, this could point you to something which was missed in the new kernel, or perhaps shouldn't have been configured. That's how I go about finding the cause of a non-booting kernel in the rare occasions I end up with a lemon.
