Both tablets are full HD, both have 8000+ levels of pressure sensitivity, and both are currently within my price range.they work well with the photoshop .
Things to consider;
Cintiq Pro:
1) Has almost no parallax.
2) Eraser on pen, no need for charging.
3) Professional Color reproduction.
XP-Pen Artist 22E Pro:
1) HUGE SCREEN!
2) XP-Pen Customer support blows Wacom out of the water.
3) Much less nib-wear than Cintiq Pro.
I think the biggest things you need to consider for this case are the size, expresskeys, and parallax.
Size:
A 22-inch monitor like the XP-Pen Artist 22E Pro takes up a LOT of desk space. If you don't have much desk space in the first place, you might need to buy a mount or arm to hold up the monitor in a comfortable position to draw on. If you have an L-shaped table layout, then you could put the drawing monitor on the side table, and the main keyboard and computer on the main table, but for a single table it's hard to imagine where you can put a 22-inch monitor without it getting in the way.
On the other hand, a 13-inch tablet like the Wacom Cintiq Pro 13 will be much easier to make desk space for. You'll probably just need to put the Intuos 3 away and that should be almost enough space for the Cintiq Pro 13, plus you will be able to comfortably reach other a 13-inch monitor to type on the keyboard behind it.
It feels nice having a big 22-inch monitor, but unless you've figured out a space for it, it's really hard to include it in your workspace (this is just my observation from using a 22-inch XP-Pen Artist22E Pro, I buy it from their offical site LINK REMOVED
The XP-Pen Artist 22E Pro comes with the built-in expresskeys, whereas you'll need to buy a separate expresskey remote for the Wacom Cintiq Pro 13 if you want to do all your work on just the tablet without touching the keyboard.
This part honestly depends on what you plan to do. If you plan to put the Wacom Cintiq Pro 13 in front of the keyboard where your Intuos3 used to be, then you're probably going to just use keyboard shortcuts and won't need the expresskey remote. However, if you're planning on drawing on the Cintiq Pro without using the keyboard, then you'll need to pay another 100 USD for the Wacom Expresskey Remote since the Cintiq Pro doesn't have expresskeys built-in (or you could do everything with finger touches since the Cintiq Pro does have multi-touch support).
Hm, thinking about it again, I guess the expresskeys aren't really a factor since the Cintiq Pro can kinda compensate with the multi-touch (finger touch input).
Parallax:
As you know, the XP-Pen has some parallax, while the Cintiq Pro is advertised to have basically none. I experienced "no parallax" with a Microsoft Surface Pro 3 in the past, and I honestly disliked not having any parallax because I couldn't see the cursor under the pen when using very small brush sizes. I am someone who wasn't ever much of a traditional artist, so I've become extremely used to watching the cursor instead of the pen while drawing, so not being able to see the cursor is unfortunately a problem for me. I've found that I actually depend on parallax to be able to see the cursor under the pen.
This obviously may not apply to you, but I figured I would mention it as a personal opinion.
For the most part, I think that the Wacom Cintiq Pro 13 is probably a better pickup if you aren't really fussy about the size of your LINK REMOVED .
The whole point of Wacom alternatives at this point and time is to offer tablets for less than 1000 USD for people who cannot afford the lowest Wacom Cintiq but still want a drawing monitor. The XP-Pen Artist 22E Pro is too close to the price of the Wacom Cintiq Pro 13 to really be considered unless you absolutely don't want to settle with a smaller 13-inch monitor and want a larger 22-inch monitor instead.
The Wacom Cintiq Pro 13 simply outdoes the XP-Pen Artist 22E Pro in all aspects (aside from the size) because it offers extra features like multi-touch, pen tilt/rotation sensitivity, and I believe it actually comes with a longer warranty (I read the warranty info and the Wacom Cintiq Pro 13 comes with a 2 year warranty, whereas the XP-Pen Artist 22E Pro comes with a 1 year warranty).
Basically I just wanted to share my experience from this huge upgrade and it would be cool to hear about your experiences for those who had an opportunity to try a graphic tablet and a pen display monitor tablet , which tool ended up being better for you?
