3 Artons cost 12k merit, but you can gain a lot more imps from imp dungeon if you have enough Energy.

3x23-25 is well over 70 imps per session for 4k merit Imp key, 3 artons is 36 imps.

Having more merit also edges you closer up the tier of rewards for total merit had.

However you do save 30 minutes of your life and takes 0 energy to use said merit.

It's all about what you'd prefer.
