I can easily tell the difference between 60hz and 120hz+, but it absolutely does not matter to me for web browsing and software development.
FWIW I do spend a lot of time with 120hz and 144hz displays.
For gaming it's awfully hard to go back to 60hz after tasting those high refresh rates. In fact, I've been saying that for 25 years. At the tail end of the CRT era a lot of higher-end CRTs could do like 90 or 100hz at 1280x1024. Most PC games couldn't push that many FPS even at lower resolutions but it really helped reduce flicker and eyestrain, even when staring at text in Windows.
