ZOOM707 vs RP100,which one should I choose?

[Ibanez270]

Hi,everyone.I'm going to buy my first multi-effects,but I can not make decision between ZOOM707 and DigiTech RP100.Somebody told me that the distortion of ZOOM707 is weak,while the distortion of RP100 is stong.Is it right? What RP100 attracts me is its amp models.The only thing I'm not satisfied is that RP100 has no expression pedal. In addition,the Wha of ZOOM707 is very good.I know RP200 is perfect,but I can not afford it. In my local music shop RP100 is much more expensive than ZOOM707 (I'm in China),which is contrary to the situation in America.(In marsmusic.com, RP100 $99.99 and Zoom 707 $139.99).I don't know the reason. Would you like to help me?Tell me which one is better and which one should I choose.

Well, I personally hate pedals like those. The sounds in them sound cheap and the distortion in them is very undynamic. I would recommend saving up for a line 6 POD or a new amp.
