I have a Yiynova MSP19U+ and I like it. I've never used a cintiq but I have an Introus 4. I love wacom and I will always tell someone to get a Wacom IF they have the money but I love my Yiynova. It's a bit bulky but it get's the job done and I've not had any problems huge problem with it. The only thing I noticed was just a slight color shift on my display but for me it's not a problem. I suggest this display for anyone looking for an alt to the crazy expensive cintiq. I actually noticed the color improve when I moved to Yosemite.
Once I get a new computer I will though get a cintiq, just bc, like Mac, it's my go to brand.
You can actually research reviews for the products you're looking at and compare. That's what I did. there are a TON of reviews and videos out there.
