It's honestly preference. Some will hate it, others like it. Think of it like going to the movies. Don't you know people who love sitting in the first 3 rows? They insist on sitting there so they get the big screen effect?
I had three 25.6" monitors in an Eyefinity setup. I liked it. The only issue I had was it was SO LARGE end to end that if you were looking at the left screen you had zero chance of seeing what was happening on the right screen. But if I looked right ahead I had no issues seeing left and right monitors. Your vision might be different. Try going to a local shop and looking at a monitor of that size. You'll find something you like.
