I play both, while they are tottlay different to use, at pve their role is the same, mob control. at pvp their role changes a lot, as a crane you are supposed to first use your debuffs and stuns and then start to kill, as a turtle you just kill and sometimes a strategy aoe stun. They arent hard to figure it out. their role is the same at pve and they change a little at pvp
I picked turtle hermit because I liked the look of super kamehameha, although now looking back I think I should of made a crane since they are much better PVP wise. I still do like turtles, just it sometimes isnt fun when it comes to pvp, so I was thinking of making a crane soon.
