Lots of people go to the BWCA and love it.  I'm glad they enjoy it and hope they continue to go to the BWCA.  Quetico and the BWCA are about the same size, but the BWCA gets 10 times the visitors.  Personally, I gave up on the BWCA years ago and only enter Quetico from the north.  Quetico is certainly more expensive and farther to drive.  But I think it is a variation of you get what you pay for.  As pointed out previous discussions, Quiet Journey members have a preference for Quetico over the BWCA.
