Well I find the browser on the iPod touch faster but considering it can only use Wifi...
There's no way to measure it against a Storm on a 3.5g network..
I have both I don't use my touch near as much as I used to with the new os my storm is pretty speedy I have a Verizon air card for my internet with a wireless router so my speed varies quite a bit on my touch.
