I have a triple rack for the every day use bikes.
It fulfills a role, and I have 2 bikes in one direction, and the middle one in the opposite direction, but it depends how your bikes mesh or not - though a block of wood can help lift a wheel if that helps with clearance.
They are quite big the spaces, to cater for mtbs I guess, so your average bike will flap about a bit, and likely lean on the spokes.
You could help reduce that by adding some pipe lagging/cable ties once you know what will go where, so the tyre leans on the lagging.
Mine was just from Lidl or Aldi, and has been fine - I have used a 2nd one in the van on occasion as well, but it's not quite as good for that task, as I find I need a bit more flexibility with how I mesh them together, individual stands I find better in that case.
One thing to be aware of, is that for my middle bike, the rear wheel is in the 'loop' - this would roger the rear derailleur, so I just need to make sure when pulling up I put it into the hardest gear so the RD won't end up leaning on the hoop.
Not a show stopper but something to consider.
