Zoom 1608 vs Boss 1600

Has any one had experience with one or both of these units,? seems like the Zoom is cheaper by a few hundres buck and offers just as much as the Boss unit except 10 tracks for the zoom vs 16 for the boss unit. looking to get one of these units soon, is the extra tracks on the Boss unit the only real diff?please advise! see link to each below...
