I use a 27" DELL (2560x1440) and after a few years of use I'd rather have two or three smaller 22-24 ones, or go with a very large 32 inch 4K. A 27 takes up a lot of space and isn't that much bigger than a 24 inch.
I use 27" monitor, it is absolutely amazing in every possible way. Definitely go for it. The only time I didn't like it was when I tried to use Modo. By default they use tiny font (and you also can't change it) and if you don't have super-healthy vision, it is practically impossible to read any text. Never encountered…
