Boaphile vs AP rack

Does anyone have experience with both of these? Specifically the 41qt? I have the Boaphile ballroom rack, but it seems very wobbly. Is the AP rack more sturdy? Will AP and Boaphile stack?

I don't have any Boaphile products but do have a AP cage and rack. I actually just ordered four more cages from AP because I've been buying but happy with what I have.

The rack I have is from their economy line. The ones with the mostly open sides and back. It is very sturdy.... As is the cage.
