Prior to the very latest generation nvidia GPUs the quality of nvenc was significantly worse than software x264. This, along with the still there even if very small performance hit, is why the major streamers all still use a dual PC setup with capture cards. If you're just streaming casually this doesn't matter at all. If this is your day job, though, you probably want all the quality & control you can get, and NVENC isn't quite there.
