Okay. Here we go.
When I first started, I was using Paint Tool SAI. It was actually a very good program, except for a few things.PAINT TOOLS SAIPros:
Dynamic Mixing - When using the brush, it would mix the color you were using with any nearby other color, making shading way easier.
Interface - The interface is very beginner-friendly, and even still good for professionals.
Customization - It is INCREDIBLY CUSTOMIZABLE! You can change almost EVERY aspect of the interface and functions.Cons:
Text - The text tool is very basic. It's one font size, and you can't even change the font face.
No Dark Theme - Personally, I prefer dark themes, and SAI just didn't have that.
Pressure Sensitivity - I don't know if this was just my problem (it probably was), but I had trouble getting pressure sensitivity to work. This contributed to me moving onto...FIREALPACA:
Very easy to learn without any tutorials
Built-in comic-sized presets
No dark theme
Pressure sensitivity - Same as above. I just couldn't get it to work, so I moved onto...MEDIBANG PAINT PRO (by the creators of FireAlpaca):
DARK THEME! - By default, MediBang uses a dark themed interface! I love it!
Pressure Sensitivity - After trying literally everything out there to try and fix pressure sensitivity on FireAlpaca, I finally gave up and got MB, where the pressure sensitivity worked immediately.
Simple straight lines - If you tap on a point, then hold shift and tap where you want the second point to be, MB will automatically create a straight line between those points.
Glitches - The glitches are very minor, but are noticable when they show up. One glitch I noticed was the right button being the eraser glitching. It would sometimes not switch back to the pen, but you can fix that.
And that's about it! I'm currently using MediBang, which I think is the best of all of these programs. I hope this helped you out!
P.S. Here's a sneak peek of a panel of a comic I've been working on in MediBang... It'll be up on my Tapastic tomorrow or next weekend.
