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?
