I've recently had the pleasure of purchasing the 30" matte Dell U3011 IPS and the 27" semi-glossy Samsung S27B970 PLS.
There are pros and cons to both. The anti-glare coating on the Dell makes black text on white background look absolutely rubbish, fuzzy and hard to read. You can sort of get used to it, but every time you switch back from using the semi-glossy Macbook it looks terrible. Black themes don't suffer from these problems nearly as much.
With the Samsung, colours look much more vibrant and text is sharper. Reflections are very much an issue, especially with black themes. In very bright conditions with visible light sources the screen becomes almost unusable.
Overall, if I could control my lighting, I would go with semi-glossy. Otherwise I would suffer the Dell's anti-glare.
I find that both fuzzy text and reflections lead to eye strain and headaches. If they could tone down the anti-glare strength (but still leave some AG coating) I would probably go for that in all circumstances.
On an unrelated note, I do prefer the 30" pixel pitch (.25 mm) to the 27" (.23 mm). At the given viewing distance the .25mm pixel pitch more closely matches my Macbook's, meaning you can use the same font sizes for both.
