So should this be a no brainer?
Not sure really, I don't know what other features the Zoom one has. The Boss doesn't have a built-in mic or drum machine buttons, but it has Virtual tracks which basically allows you to record 8 different takes on the same track so you can choose your best, or keep the original raw tracks when you bounce down. Kinda hard to explain, but dead handy.
It's also got post-record EQ, reverb and chorus/delay (one of the other, cant have both) and "Scene" saving so you can have totally different EQ, reverb and chorus/delay settings for the same song to compare to see which is best, or whatever.
And you can cut/paste/delete/edit the individual tracks which is dead handy if you fancy doing drumloops or something similar.
*quickly looks at menu on BR8*
And an expression pedal in for the built-in whammy/volume fx, a center cancel (sucks out the track down the middle which is normal vocals, for a karoke effect), a digital out, a MIDI out, a tempo map for different bmps/speed up/slow downs for the drum machine through the song, song markers with "punch in" footswitch jack and some other stuff.
But like I said, it's quite possible the Zoom does all this stuff too.
