I wouldn't say so, for most people what you have done is good enough. However there may come a time where you have to do something janky, at that point you'll probably wish you were on a different distro, but for 95% of people, they will never run into any issues with mint.

Sounds fine to me. What i meant to say was that since it's all linux, the distro you pick is just customized for a certain usecase, but you can pretty much do whatever you want to do with any distro, but if you don't want to bother setting it up yourself, a distro that is already configured a certain way is more convenient, but which one is "best" in that case purely depends on what you want to do with it, but there isn't really an absolute "best" distro that everyone should use.
