Hi! This is a comparison of lots of art programs. Remember that this is just my opinion and you can use/do anything with any art program. I hope you find this helpful!! If you have any questions about any of these art programs, just ask me in the comments! [EDIT IMPORTANT!!!] Photoshop just added a stabilizer, it's not as good as CSPs, but it's still nice. They also added all of Kyle T. Webster's brushes for free, which are cool if you want your digital art to look traditional. Overall, photoshop's a lot better than it was before, but CSP is still my number 1 fave! [EDIT] Medibang also has more brushes, including the marker brush that you can download with the creation of an account.
All art except the art program logos, were made by me. Please Note: Clip Studio Paint has a trial version, but you can't save your work. You can use the trial for as long as you want. I have heard of people just taking a screen shot of their art when they are done. PhotoShop has a 1 month free trail.(Mine glitched and I had it for 3 months??? Probably because I never restarted my computer) Paint Tool Sai has a 1 month trial, but it's only for windows.
