No, but for a different reason....

>First, let me admit that I regard a bench as a utilitarian device used in the aid of making furniture and other stuff. A means to an end. Something one makes to be able to make furniture and the like. When friends drop by you show them the new cherry dining room table you made, not the bench used to make it. The bench should be covered with shavings, parts and tools and dinged, scared, stained and dabbled with glue spots. Not the sort of thing one shows off.
Someone bought $200+ maple from us for a bench and among the pieces purchased was an exceptionally curly plank. It got glued into the top. Had I known I would have held that curly piece for someone that would have made something special out of it. I considered it a waste to use what has become a rare piece of wood for bench top.
One presumes the bench will be used to turn this oak and cherry into furniture as soon as there is a bench to work on. The only useful requirements I see in bench wood is that it be flat and heavy; and light colored for better visibility, but that can be fixed by painting or a layer of light colored laminant.
I can see no reason to use $8/ft cherry ( as rare as good quality cherry has gotten) when $3 a foot ash or whatever will do. Buy what you need to make the bench and save the furniture wood for furniture. Any wood makes a good bench, except maybe white pine or basswood. Maybe your supplier has some maple heartwood or wormy maple you can get at a good price or any other appearance-defect, heavy, stable lumber. Mine is poplar and I got the extra weight with thickness (3"). Even some slow growth yellow pine (dry) would make a suitable bench.
