How do Gunslingers and Hermits Compare?

When do Hermits win out? From 10+ or after level x?
When Hermits train, it's just SP, booster, haste, L7. Do 3rd job Gunslingers train a similar way with Burst Fire, or do they take advantage of their summons?

It's not just spam triple fire for 3rd job.
Timing a Lv20+ gaviota in between your triple fires every so often helps rack up damage and if you're at a stand and snipe type place like newties, octopus is amazing.

Cooling effect is a must for enemy incapacitation, you take less to no damage with it.

and booster is our only buff lol
