I've never used a HastyBake rack but I can tell you that a MAK rib rack is the LAST rib rack you will ever need to buy. Super sturdy stainless steel that goes right into the dishwasher and comes out lookin great. It's super wide so the racks get the support they need and it will hold 8 racks of ribs.
It's designed to hold 8 racks but can hold 10 in a pinch using the handles on either side to hold two more racks. And it fits in a drum perfectly.
