OBS is much more aimed at livestreaming to platforms like Twitch and managing multiple cameras incl one of you, one of your screen etc. Well beyond what Cap is for.
But yes, use the most specialized tool for the task at hand.
Cap completely ate several recordings for me. Admittedly they were over an hour long, and I should’ve broken them up a bit, and perhaps it’s not what it’s used for. Switched back to OBS, while it’s not as easy to use it’s pretty reliable
