Is it better to Quest or Grind while multiboxing?

[Stealthy]

At level 60 I get 5,000 exp per pull X 4 (raf) with about 2,000 exp for non rested non raf leader, at the seige engineers in epl. So 22,000 total exp for under 1 minute, tag boosting. Mobs repop in like 7 or so mintues but by the time you loot and drink it goes fast. I maintain between 60-70Kexp/hour without any problems.

But it does come down to what you really like, if questing is like a job then why do it, if grinding is like a job why do it?

I like killing mobs lol.

Bear in mind that under RAF, with 3 times the exp on quest turnins, you would be getting 27K (on average) per quest turnin. Since it takes you 1 minute to clear the mobs, and 7 minutes to wait for respawns / looting, you're getting 5K exp for every 8 minutes - in other words it's taking you approx 43 minutes (8 minutes x 5.4) to earn the same amount of exp as you would turning in a quest. I understand that you like killing mobs, but I think you could easily be earning 3 times the exp, maybe more, from questing.
