You will be able to get better tones from the Line 6, but the lack of foot pedal makes it quite difficult in a live setup. You will only be able to use one patch per song. Also it's tiny, your fingers might push you onto a Bumblefoot patch! :-[
Maybe with your pricerange go for the Zoom G2.1u which is usable in a live setup. I know because I use both of them.
The Pocket Pod is more for practicing but the tones are very true.
The Zoom also has an expression pedal which is great as a volume control or for assigning an extra effect, e.g. digital delay or reverb, or whatever you want.
Dont know the Behringer
