What are the pros and cons of stepper motors (think NEMA 17's) vs large servos?

I've not really done DIY robotic stuff before, and was wondering what the differences were between stepper motors and servos.

From what I could tell when I compared NEMA 17's to various servos on amazon:

NEMA 17 Stepper Motors:
more precision

heavier

less torque (84oz-in max for NEMA 17)

not restricted (can do full revolutions all day no problem)

faster

Servos:

lighter

less precise

more torque

slower?

can't rotate freely like stepper motors

Is there anything that I'm missing?

You have mentioned all things that are necessary for everyone to consider before going for stepper motors.
