Hanns-G 24.6" vs ASUS 24"/25.5"

Newegg july 4th sale has this monitor up for $199 flat free shipping...it's a bit tempting but I'm not so sure if the quality on the hanns are pretty crap compared to other brands. I'm having trouble debating between this monitor and the ASUS VK266H(25.5" ) or the ASUS VK246H(24" ). The VK266H is 1.5 inches larger in real estate and has the 1920x1200 resolution vs the 1920x1080 the other two has. Also it's going to be 299.99 after rebate.

So I'd be paying 100 dollars more for the resolution, extra size and slightly better contrast. Is it really worth jumping from 24" or 24.6" to a 25.5 to warrant the extra 100 dollars?

I'm not looking to jump above $300 btw. Thanks for suggestions.
