Volume - If you want the loudest, get the Birch floor. If you don’t want as much volume (i.e. practicing in a bedroom or an apartment) get the
Original floor.
Durability - While both are durable, I believe the
Birch floor is more so.
Slipperiness - The Birch floor is more slippery when you first get it and won’t become less slippery until you’ve tapped on it for a while. The
Original floor is not too slippery.
Appearance - The surface of the Birch floor is definitely nicer looking, but I personally like the covered edges of the Original floor. This is a toss up.
