If you are a laptop user, you may want to avoid driver version 550 because there is a megathread on the NVIDIA forum where users are reporting that this version is making their distributions randomly crash.
One of the biggest problems regarding Nvidia drivers is the fact that a small minority install them using Nvidia's .run script, which overwrites important libraries, resulting in a wide range of issues. I've always installed Nvidia drivers using my distro's package manager and I've never had an issue.
