Which is a better exercise

Well crunches will target your upper abs more than the lower abs. Likewise, sittups will target your lower abs more than the upper. I stopped doing sittups and I do about 200 crunches a night. I do modified crunches so I work my obliques as well. It all depends on what part of your abs you're looking to tone.

thanks I appreciate it.

Whats the difference between a sit-up and a crunch? is it just that with a sit-up you stay straight, and with a crunch, you curve more so your shoulders get closer to your knees?

A crunch is performed in a position that keeps your back flat on the floor and you lift your head/shoulders toward your knees - as opposed to bending at the waist to "sit up". They can be modified to be more challenging by "bicycling" your legs and keeping your feet off of the floor at all times.

Try doing cable pull down crunches with a rope. You are kneeling on the floor. Twice a week and your abs will explode.

Hanging leg raises off the end of your bed is also very good. Works the lower part of your abs. I sometimes do these at night before bed on my ab days

The better excercise is the one you will do with proper form consistently.

Basic crunches isolate your upper abs, sit ups utilize hip flexors at the top of the movement in addition to the abs.

emma72 is only partially correct, your back is on the floor but the contractions of your abdominals curl your head and shoulders toward your knees (bent 45).
