W2 vs 1099

Anyone have a good resource on how to decide whether to go 1099 vs W2? I have read quite a but about on WCI and other sites but still found myself a bit confused. If pay is the same, does it make most sense to go W2 as the employer would be paying for social security and would have less tax obligations? I am currently all 1099 with my jobs and wondering if I am screwing myself by not picking a W2 contract instead. I mostly work as needed at a few different sites.
