OBS is my fav. one. If you're using Nvidia, Shadowplay is a good alternative.
I have tried using Fraps but it seems like I was too retarded to set it up properly
Bandicam is the easiest and most straight forward; for games i really like PlaysTV especially since the newer updates since its much more stable, has a really simple editor and you can bookmark and save like a 4 minute clip in game which is super useful in admin sits
I prefer to paint what I see on a canvas, then send it in to my local art museum where the museum nuts will put a ridiculous price tag on it because someone vomited color on it. Then they'll have it sold for an entirely different price cause they're retarded.
