I think it depends on what you are looking for. While Linux Mint is a safe option, it does have some drawbacks... well it's more drawbacks from Ubuntu but as Linux Mint is based off of it, it's also impacted. Primarily the fact that Ubuntu packages are terribly out of date. Thankfully mint makes adding PPA's painless, but for apps that don't have a PPA it's a pain to install them from scratch like Mangohud. It's not impossible, but there is an expect level of Linux knowledge which is required before going in.

Another option is Manjaro. You will hear the litany of endless criticism about it from the community, some of it is valid. But for the most part, while it's not as nice as Linux Mint, I think the OS will get you to the point where you can start using your machine faster. Mostly thanks to Arch's rolling release, as well as the AUR for filling the gap between official packages and flatpaks.

I was using Manjaro for the longest time, but switched to Mint due to a freak bootloader accident. I prefer Manjaro in terms of how well it handled Games and Windows software due to it's association with Arch. But I like how well Mint manages my laptop's battery and performance or lack thereof due to it's pitiful cooler.
