Whats smarter?

for you people that dont know monsters in maplestory, this may be a little confusing.
just bare with me.

i recently got to level 120 which makes me a lot more powerful and i have new job skills
i have a skill called "chain lightning" which attacks 1 monster and goes on to attack 2 more.
i was at a map with about a mob of 30 where it took 3-5 hits to kill a monster and i got 1800 xp per monster i killed. (monsters are level 11
than i thought about a map where i was at a lower level, with a mob of about 100 on the map and give 600 xp per kill.
now these monsters are a lot weaker and with chain lighting i kill about 3 at a time instantly which sums up to 1800xp. (monsters are level 80)

which ones do you think i should train on?

Lower level.
Better because less pot usage and faster exp.

thats what i was thinking, and they drop ilbies which i can sell for about 4mil a piece.
