BB is it really good.

Well I hate my sand, so put me down for BB.

I would switch it in a heartbeat if it wasn't so hard to do.

The key is bioload and balancing your waste management. High bioload + a Sandbed is a recipe for disaster in the future. Unless of course you are the worlds best water changer. A sandbed will mask your high bioload problem until it no longer can, and then you're in for some major problems.

Having no sand will not mask this problem and you'll be forced to deal with it before you have major long lasting problems.

Flow is the other area of concern, 'high' flow rates are not possible using sand as it won't stay put. Flow is the #1 overlooked important thing in this hobby, water movement makes everything possible. Stagnant tanks aren't good for much..
