Hi can anyone do a conparison about samael and mishi as base?

From what i heard people keep telling me samael for warrior, mishi for rogue but they couldnt tell me the specific differenct between these two

The best information i could get out is that samael has hp and mana regen and mishi only has mana regen

I would like to know more like if the mana regen in mishi is faster than that of samael and what other factors will contribute to sam > mishi or mishi > sam

Thanks in advance! Have a nice day
