I like solid wood stand, not any particle wood or other substitute. Paricle wood does not do water well at all. I also like to do a heavy coat or polyurethane on the inside of my cabinets for even more protection. It'll get wet and damp down there. Of course, all this applies to
SW tanks for me, but something to think about and help you in your
FW decision.
Also, do the 2 doors give you more room to work underneath? If so, go for more room and solid wood
IMO.
