Vex sensors are nice for the most part. They're already wired for a PWM signal (the pins have to be changed to female though) which is really nice and they're fairly accurate for the most part.

The Encoders are pretty good from what I remeber, The line followers are really nice, the light sensors are kinda hit or miss, and the Ultrasonic Sensors are good to about 5 or 6 feet reliably.

As for the Limit Switches, they're good for small applications but I would make sure they're very well protected. The Bumper Switches are really nice though, I've never broken one and I'm not nice to my Vex stuff.

I've never used any of the never stuff like the Potentiometer or Accelerometer but they should be pretty nice.
