It is fun to do at times but in my experience, the gaming experience is not nearly as good as it is on a monitor.
Depends what you care about most, and if it's used for purposes other than gaming, like movie watching, net surfing, etc.
What I find strange is a lot of gamers rave about certain monitors, just for things like fast response times, or high refresh, or G-Sync/Free Sync, yet most made for gaming so called high end monitors with such features, have just cheap TN panels.
TN panels are way lower picture quality due to being only 6 bit color depth, which can show in color banding, inaccurate and often blurred flesh tones, and lousy viewing angles. So yeah, if all you care about is fast response, high refresh, and frame syncing, you may be all right in some respects, but you're going to have crap picture quality compared to an 8 or 10 bit panel display.
