OBERHEIM SYNTH

Hi group.  I recently purchased an Oberheim 1000 and a 6R, listened to both and like what I hear, but think I only have room for one of these babies....decisions, decisions.  Here is what I am weighing....1000 presets, editable via software in mono before external effects or 100 presets, editable via front panel or software, in possibly stereo or layered, but limited to 4/2 or 3/3? voice division.  Sonically, the units seem the same although I have not tried an apples with apples voice comparison....so what are your thoughts on which I should keep?
