If you have a newer Shimano 3spd,you use a 3mm hex to remove the shifter box,then it's just the 15mm nuts. If you have a Nexus 7 or 8 with integrated roller brake,then it's a whole different story. And if you have the Euro-spec roller brake,like the ones that came into my clinic last year,then I would suggest getting a new hub.
On my derailleur/disc bikes;flip bike upside-down,pop QR,remove wheel. No IGH hub is that simple.
I guess it depends how fast you are. Some people can change a tube in under a minute. It takes me a little longer.
Some tire/rim combinations are challenging and I can spend more time fighting to get a tire back on than getting the wheel off even when I had a roller brake. I used a wing-nut and a hex bolt to make detaching the roller brake easier.
While it can take a bit longer to change a tire (not that much really) I don't see it as a reason to shy away from an IGH, - unless you're constantly dealing with flats.
