Has anyone used both Meguiar's NXT wax and Speed Detailer and Griot's Best of Show wax and Speed Shine? How do they compare? Which do you like better?

I've been using Meguiar's NXT products since they came out a little over a year ago. They are pretty good and I am happy with them. I have never tried Griot's stuff and I was wondering what people who have used Meguiar's thought about Griot's before I spend the $$$ to try them out.

Thanks for the inputs.
