I used them in my 2e games. In hindsight, I would not do so again. It lead to people complaining "why did that PC get more XP than I did?" and having to explain every time I awarded experience. And with the subjective XP bonuses for role-playing, there was some grumbling a few times.
Yeah, I only played in one AD&D game that used the individual rewards.
However the other games tended to have generous rewards for things like good roleplaying and achievement of goals. There were some individual rewards, but oftentimes it was for the entire party.
