Hands down the Boss GT-8. This effects processor blows the Pod out of the water. The reviews here are probably based off the factory settings, and obviously no tweaking was made. It takes a while to get the hang of, but when you do, you'll be in tonal nirvana.
Don't be biased by the fact that you can record directly from the pod. I'm pretty sure there will be latency issues, and you could just hook up a 1/4'' cable with 1/4'' to 1/8'' adapter (that you can find for 50cents) and put it in the line in of your sound card with the GT-8.
I've played gigs with both processors, and the tone of the pod was nowhere near as good as the gt-8. Trust me, get the GT-8.
