I don't like the way the Zoom pedals work, they may have a nice sound, but they're not enough tweakable for me (for example, the delays: I can never achieve what I want).
I'm partial to the Yamaha Magicstomp, but it's not very good on distortions, I'm afraid (probably the Zoom B2 is better distortion-wise, but my opinion is that you can always buy single distortions, a Bad Monkey costs nothing, a PD-7 likewise, so why bother with cheap digital pedalboard distortions?). Even though... well, I really liked the fuzz, for a synth-like sound (slow and fat notes), plus distortions can be EQed twice, pre-effect and post-effect, which is neat, I think (you can feed more treble to the distortion, to get a harsher effect, and then add bass afterwards, to get more beef).
On the other hand, it's super tweakable and the effects are very good (especially modulations, reverbs and delays... I actually prefer the Magicstomp's phaser compared to the Small Stone, for example

).
