When I try to use biscuit joinery, no matter how careful I am, I always tend to cut one side higher than its mate on at least one joint. The only fix is to recut the slot which makes for a real sloppy joint.
These days I reserve biscuits for stuff I don't care so much about, like storage/utility boxes.
Since the pieces are already cut, I would opt for dowels.
Should you "miss" with a dowel, you can always glue a piece od dowel in the misaligned hole, cut/sand flush and re-drill. Very forgiving process.
Just my .02
