Beside this, is Krita better than Paint Tool SAI?
Krita is great for almost anything, and freely available on all platforms, but lacks some post processing tools such as automatic healing, etc., but can certainly do the job. Paint Tool Sai is great, but is not free, and available only on Windows.
Also Know, is FireAlpaca a good program? The good thing you can do is move each panel anywhere you want. That being said, FireAlpaca makes a really comfortable software. THE BRUSHES: This software allows the user to do things with brushes that isn't possible in many other software. DOESN'T TAKE UP MEMORY: FireAlpaca is a pretty fast and fluid software!
Keeping this in view, is Medibang better than FireAlpaca?
Honestly the only difference i see in medibang and firealpaca is that one has cloud and also better brushes (medibang basically). Im also not sure if parblo is a popular brand but its always been working fine :0 Ill admit that medibang is also better, but I also wouldnt say that Firealpaca is THAT bad.
Is Krita a virus?
Now, we recently discovered that Avast anti-virus has decided that Krita 2.9. 9 is malware. We don't know why this is happening, but as long as you get Krita from the Krita.org website it shouldn't have any viruses.
