I think to answer the ops question one would have to first define what is 'quality of life for a fish'; esp in the aquarium.
Then there could be all sort of side debate - is an angelfish better off having long fins but a 500 gallon aquarium or short fins but a 29... live food or dry food... anyway i always cringe at threads along the line of 'quality of life' or best this or best that.
having said all of that i tend to find wc or wild form of fishes healthier in most cases and in some cases truly fantastic looking as is this wc fish:
Of course the care required to keep and breed that fish is very different than your jumbo wondo guppy where your 5 year old sun can toss it into a cup and if it dies he can buy 5 more because the store can breed 10,000 an hour...
So there is that trade off.
