What is the sweet spot for experience gain? Is it more effective to fight the highest level enemies I can find, or am I penalized for being out of my depth? Are certain areas of the game better/best for experience gain/leveling? Are bosses better than areas with infinite minions? Would I get exp faster in a higher-level co-op game? What are the most time-effective techniques for rushing/boosting a character (either solo or co-op)?

Experience & drops
Is experience gain individual, divided/split between players, or duplicated for each additional co-op player?
Each player gets the same experience. It is not split between them (like credits), but everyone gets the same amount (like ammo).
Do you get experience for others' work when you aren't in the same area of the map?
You have to be relatively near an enemy kill (but not that close) to get the XP. (I think.) But quest experience is given no matter who turns in the quest and no matter how far away they are.
Do all players get the same quest rewards?
All players get the same rewards, with the exception if the quest gives different guns per class or random guns. If it's a single item, it will simply drop into your inventory if you weren't the one to turn it in. If there is a choice of items, everyone will get the mission accept dialog to choose their reward individually.
How are experience, difficulty, and item/money drops affected for each additional co-op player?
I don't have exact stats, but there becomes more XP/items/cash and increased difficulty for each additional player.
Does the area difficulty scale to only the host's level, or does it accommodate/average difficulty between all players?
Host level, just like Borderlands 1. (You can twink low characters this way, as long as they don't get themselves killed everyone 10 seconds, I guess.)
Large level differences
Some games have disincentives when characters with large level differentials play together—is that the case in Borderlands 2?
I haven't researched this, but I think the mechanic is similar to the way Borderlands 1 worked: meaning the XP is shared (not split) no matter your level.
Are higher-level characters' stats adversely affected when joining a lower-level character's game? Or vice versa (boosting a lower-level character using a higher-level character's game)? Are experience gain or money/item drops diminished/impaired with large level differences? If so, what are the specifics?
It doesn't appear to alter the play stats or drops for differing levels. Basically, the host determines the level of enemies and drops, with number of co-op players increasing difficulty of enemies and amounts of enemies and item drops. (Though this isn't confirmed yet.)
He's a Gunzerker, and their brawl tree have health regen abilities, being a "tank" class. Especially, from that link:
Level 22-31 – Alternate assigning points into Ain’t Got Time to Bleed (first) and Last Longer. Health regeneration and longer Gunzerking is what you’re all about when tanking for the team.
and
Level 37-41 – Max out Sexual Tyrannosaurus (really?) that gives you health regeneration while taking damage. In other words you will be in god mode for real.
Also, there is a legendary shield that regenerates life (source: Borderlands 2 wiki)
Neogenator, Anshin, Legendary: Regenerates health when active. Damage to shield increases health regen rate.
Best Answer
Kill flesh stick again and again in the Tina special guest quest. best if your coop partner stays by her and keeps beginning the mission while you are where he spawns waiting for him with a shotgun or else. at lvl 14 its 1800exp every time. i leveled to 20 in 5 minutes.
Note: If you restart the quest too quickly fleshstick will stop spawning and you will have to reload the area. To avoid this, wait until Tiny Tina finishes her line ending with "my abode". If you mess up, first she won't speak her next line. If this happens, wait a minute or two (to let Tina finish the sentence, even though you can't hear it) and start the mission once more, Tina should talk again.
