Which missions give you the most XP?

Regular?
Tip?
AE?
Any other (besides TFs)?

Thanks.

probably any large open map, like the circular pit graveyard, axis america ruined city map, etc.

there probably isn't a 'best mission' for XP. how about just running arcs, you'll get the bonus at the end which will help with your XP/min average, which is more important overall.

Hell if I know. Here's what I do. When I am on a character that wants fast levels, I form TFs. Non-speed, kill most TFs seem to get me plenty of XP and I enjoy that playstyle. When I am powerleveling someone, I run Borea missions at +3/x8, because I have several characters that can handle those missions and they go fast.

Croatoa's end xp bonus for arc completions is abnormally large. Granted, one of the arcs includes the infamous "30 Fir Blog" mission. Red Cap bosses hit like a Mac truck so melee types can have issues with them. Still, four contacts in the 25-35 range that offer a nice setting and change of pace from the rest of the game. The stores offer bad exchanges rates so take an extra minute, or so and sell outside of the zone. Why it was done that way and continues to do so is beyond me.

Side note, just by doing any arc you also get merits for it. You can use Oroboros, or the one base item to get old arcs.

Freakshow use to be abnormal in the amount of exp they gave likely due to the fact that they rez, but that was tweaked. I still think they give out rather decent exp though.

Run missions on x8 even if you don't have 8 members. 6 people should be able to handle x8 fairly easy and the exp would be a factor of 1.3+ versus the normal 1.0.

For solo play, any character that can stealth missions can load up on missions that isn't a defeat all and just do the minimum. This will counter the lack of exp for killing everything with getting more mission completion bonuses in a short period of time. There is a day job that let's you get additional exp for every mission completed. Blueside, log out in a police station to earn the day job for it.

It's been ages since I've done this, but I do remember running missions in PvP zones and those gave recent return on them. Granted, I know for at least one zone you fought Arachnos, who aren't the easiest to take down, so I would rank it rather low.

As Amy said the Croatoa arcs give really good end experience bonuses.

Don't forget that doing the Weekly Strike Target on a character that's not 50 grants about half of an entire level in Exp at the end of it as a bonus. Not sure if this is repeatable or just once a week.
