Granted i havent tried gimp 3. Ill have to give it a try. But im so fast with ps. And i hate how each program needs to have their own control schemes to differentiate.
I just dont get why people hate photoshop to the point of being unhelpful when people ask how to get it working. Especially when many people are pirating it anyways.
It takes a while getting used to anything.
Gimp does have a Photoshop keyboard shortcut preset, to ease you into it.
And gimp does have some parts that are better. For example importing a bunch of images and lining them up on a spritesheet is both faster and easier on Gimp. And both Photoshop and gimp have scripts to do this, but I was never able to get the Photoshop script to work.
(The stable version of Gimp is 2.10.38, and even the latest dev snapshot -- which is what I assume he means by "Gimp 3" -- is technically "only" 2.99.18.)
The problem that arises is that you have to remember three different UIs and run them all simultaneously which I've measured use up more RAM, which sometimes reduces my efficency and increases my system resources more, instead of using the shit UI of Photoshop that the whole world decided to accept as the defacto standard to duplicate
It is all keyboard shortcuts, though, and you can configure them to all use the same ones. I believe they have a "Photoshop-like" preset you can select too.
About the RAM, I'm not sure what can be done. I guess it is a tradeoff. I'd probably go with more RAM consumption over Photoshop because I have a lot of RAM, but not everyone do. Considering the price of Photoshop if you didn't pirate it, it would be cheaper to buy and install more RAM, though.
I've been using Gimp for simple things, and it's been OK once I realized that whatever I want to do, I should look it up first instead of just trying to figure it out through trial and error.
