Individual XP allows me to give out individual rewards
XP is a reward, and not everyone does the same so not everyone should be rewarded the same. I rune a very RP oriented game, sometimes a few sessions between combats. Combat XP is less then half the total, the rest is story award, RP bonuses, etc.
For RP bonuses, I keep a few stacks of poker chips at the table. If someone does something particularly in character (especially when it's not the best choice), me or one of the other players will throw them a chip. Side conversations can be happenign while I working with part of the group, and it gets "noted" in terms of RP XP if a player gives another chip. I'm lucky to have a mature band of player and have never had an issue with it. At the end of the night I collect the number of chips, and they are the major factor* in determining how the pool of RP XP I assigned for that session gets divvied.
We've had player be absent, and their character was so memorable and real that other players are spouting off catchphrases and actions and that character is getting chips. Because they've built such a memorable character.
People get immediate rewards (a chip) when doing something well, it really encourages it.
I also give out XP rewards for fleshing out things of our campaign wiki.
Now, people still level around one session of each other. But the "simplicity" of tracking one number instead of five would lose so much richness with people getting recognized for their outstanding RP that it's not worth the trade off.
Just a question for those who level everyone at once - how do you deal with characters that are a level behind due to death?

* Chips is the major factor. Other factors are: everyone gets 2 virtual chips for having a character there, so everyone will get some share of the pot. Also, since I didn't want people not giving out chips because it "reduced their share" of the pot, each chip is also worth a small straight amount of XP - 5 per highest character level. On a normal night, most players get 3-6 chips.
