Spa disconnect

[OU812!]

Would like some advice. Are all disconnects basically the same? What brand would be best to use? Would like one with a built in GFCI? Also, I've seen some pics of disconnects that have what looks like a red shut off switch. Is that for an emergency shut off? My hot tub is a marquis 3 pump system. Says in need at least a 50 amp disconnect. Thx.

for the most part they are all the same/similar however some of them include VERY VERY cheap breakers that can sometimes fail prematurely or not even work out of the box so I would avoid scouring all over the place for the 'cheapest' one available and try and find something that has good Siemens or Cutler Hammer breakers in it. Good Luck!
