The software is really simple and fast to use. It's really soft for the computer compared to other softwares loke PS. With everything you need. Big amount of possibilities with brushes. My favorite is the perfect pen stabilation for the best lineart. It can be use by begginers and profesional artists because is super easy amd fast to understand to understand, it's not overwhelming like PS' layout.

The quality of the line art and pencil tools works incredible smooth. Inking with SAI and blending colors its so nice. You can't do that kind of lines and mixtures using Photoshop,vbut the good one is that SAI is compatible with Adobe, so you have the best of two worlds. Another one good point is that SAI doesn't needs much ram or memory space.
