I have to agree, Photopea really is the best alternative to PS for Linux users. It's honestly good! I wish Affinity would consider launching a Linux Verizon, as I actually like that a lot more than PS, but that seems equally as unlikely...
So for now, Photopea seems the best option overall. One plus, being written in WASM (probably using Rust?) it's really speedy and fast. It feels faster than Gimp anyways, which is definitely not a good statement on the state that Gimp is in...
This has already been disproven, due to the fact the method the researchers used to test how well it was doing was flawed to begin with. Here is a pretty good twitter-thread showing why the methods they used were flawed: https://twitter.com/svpino/status/1682051132212781056
TL:DR: They used an approach of only giving it prime numbers, and asking it if they were prime numbers. They didn't intersperse prime and non-prime numbers to really test it's capabilities at determining that. Turns out that if you do that, both the early and current versions of GPT4 are equally bad at determining prime numbers, with effectively no change noted between the versions.
If you're going for a similar Fedora-like experience, with it being a rolling release that is still stable, then OpenSuse Tumbleweed is definitely you're best bet.
Now, if the rolling release nature is something you're less attached to, then some good options would be Pop!_OS (especially if you have an Nvidia card), another Ubuntu-spin like Kubuntu perhaps or even KDE Neon, and maybe Debian 12. Though for the last one, although it's a fantastic distro, it looks nice, new, and shiny now, but in 6-12 months when you're not even half way through the Debian upgrade cycle and still on old software, will that bother you? If the answer is yes, then look elsewhere. Otherwise, Debian 12 may be a good choice for you as well.
Personally, at this point I don't fully understand why someone would choose to use Fedora over something like OpenSUSE Tumbleweed. It's such a fantastic, rolling-release distro, that's super stable, easy to work with, has some amazing tools to work with it for more experienced users (YaST), and now it also means you aren't involving yourself in the chain-of-FUD that is arising due to RHEL's incompetence.
While I agree that Debian 12 is great right now, I'm curious how those opinions will hold in 12 months, when Debian isn't even half way through it's update cycle, and people realize they are now a ways behind other distros with regards to package updates.
I love Debian as a rock-solid system. But you have to know what you're getting into with it too.
