In general lines, LiPos are lighter (for the same capacity) and maintain a more flat discharge curve versus time. Lipos don't peak, so if you're looking for punch like on electric racing, you won't find that out.... but you will certainly find longer run times.

in summary you can find on the pros:
+ lighter for the same capacity
+ longer run time
+ very low self-discharge rate
+ very flat discharge curve

in the cons:
- you need an special charger (CC/CV type)
- special care should be taken, as any battery chemistry (just a reminder)
- fragile (care should be taken to avoid punctures and physical damage)
- the battery don't peak, thus there is no high voltages waiting for you....
- they burn, don't explode... but again, which one is better?

hope that helps as a summary... anyway, there are several threads on this subject on rcgroups or here on electric on-road, do a search around.
