This is how I handled XP in the last three long-term campaigns I ran:
3e: I didn't calculate XP, just assigned it. Every PC had the same XP total, there were no individual awards. Therefore, every PC was the same level. If you joined the campaign or opted to play a new PC (for whatever reason), you started with the party XP amount. You might ask why I bothered to have an XP total at all...
4e (multiple DMs): We scrapped XP completely. Everyone was the same level. We leveled when the DM said so.
AD&D: I calculated XP the old-fashioned way (it was oddly... soothing). Each PC had an individual XP total. New PCs started with the party average. There was some level disparity thanks to the AD&D's different class XP requirements, also from things like draining and XP boosts from powerful items/weird magic-y things.
For our 5e campaign, which is converted from the 4e one, no XP, just levels doled out by DM fiat.
Our campaigns aren't so focused on gaining levels, they're really more about good characterization & amusingly ludicrous fantasy exploits. The reward for good play is itself. And given our infrequent play schedule, anything that slows the game down with repetitive tasks --which is kinda unavoidable when XP farming -- isn't going to work with my group.
re: level-grinding... that's really something I associate w/CRPGs, particular those of the console Japanese variety. I'd be interested in playing a sandbox-style campaign which operates closer to the pure strategy game model, but my strengths as a DM/setting creator lie elsewhere, so that's not something I'd likely run.
