A DSLR will give you much better image quality, high quality high ISO shots, and versatility. The downside is that it takes a lot more photographic knowledge to use, is much more expensive, and heavier and bulkier to carry.Originally Posted by jessepizzles
Based on your short question, you would probably be better off with a P&S. It will do pretty much anything you want, it's smaller and simpler to use, and requires little, if any, post-processing. The image quality won't be as good but you have to specifically look for the differences in most cases. High ISOs are usually pretty bad.Try them out at a store and get one with a short shutter lag. IS is also a good option.
I have both a P&S and a DSLR and use each one about equally depending upon what I'm working with.
