I have an XP Pen 16". It’s fine, does what I need it to do (and I like it). My two quibbles are the pen doesn’t come with a felt nib, so you don’t have that extra bit of friction, and the screen is straight up glass (as is the Huion I believe, they probably get their screens from the same factory), rather than having a slight matte texture I remember wacoms having for better pentip grip, although you probably get better screen quality without it (haven’t drawn on a centiq for over ten years though so maybe things have changed.) The bonus of my XP Pen being a nice screen is you can tilt the stand down all teh way, and the screen stands almost vertical, so you can use it as a second moniter… my daughter has been using it for home schooling on the chromebook. The stand also let’s it sit very nicely at whatever angle on your lap (hooked up to a laptop or whatever with wires) if you want to draw on the sofa without killing your back.
I use almost exclusively Clip Studio these days, it’s just so much better geared to drawing and digital painting than Photoshop. Sketchbook is very nice for quickly … well, sketching, but when you want (comic style) panels and borders etc, it starts to show it’s limitations, I found.
Art Rage is great for painting simulation.
What’s great about all these programs is you can actually buy them for a normal price, unlike Photoshop which is an expensive subscription that can’t be justified if you’re just a hobbyist or doing light freelance.
By the way, a lot of my friends use Ipad Pro or MS Surface to have that easy to throw in a backpack functionality, since they are actual computers, although with the ipad you’re locked into their restrictive ecosystem, I guess.
