Best 2k monitor for macbook pro retina 15" 2012?

Question

Monitors

I got confused in the options and reviews, either the picture from which everyone's eyes get tired, or the massive marriage that later appears (there is no time to rush around the services). Tell me the best option, well, or time-tested - from 23 inches, so that it goes more or less - for a user spoiled by retina. I just want to buy it and turn it on (it’s clear that there is a risk of marriage, that’s not the point - I hope I conveyed the essence) ... I haven’t worked on a monitor for 5 years, so I’m behind in this matter, reviews and search did not give a clear answer ...
In terms of tasks: a lot of text, I DO NOT do photo / video editing, the goal is to increase the working space to the optimum possible, so that I don’t look at the soap and don’t cut my eyes about the pixels
