Does anyone have a preference of fresh water over salt water fish? I grew up on eating tiny little perch a relative of the walleye. We would catch about 40 of them filet them and then have a big fish fry for breakfast. In my mind perch and walleye(pickeral where I come from) are the best eating fish.
I think this largely depends on what type of fish you like (firm, flaky, white, dark, etc), and where you were raised etc.
The above mentioned perch and Walleye are IMO the best coldwater/ freshwater fish there are. In the more southern Regions, Crappie are as good as it gets, but IMHO Crappie have to be extrtemely fresh to truly be their best (kind of applies to all fish but crappie change quicker than most) crappie in michigan aren't as good as perch IMO, but down south they might be better. And of course ice fishing produces better tasting fish than summer time fishing will.
There are a couple of saltwater species that I would put above Walleye perch and Crappie, but not by much. At the same time, Salmon and Tuna are a totally different flavor than other fish and therefore I don't usually try to compare them. If it swims and is legal I have eaten it. and have found nothing except sea urchin that really didn't appeal to me. The urchin was O.k. as far as flavor, but the texture would turn away most folks I'd guess.
I will not eat any freshwatwer fish Raw, but do not hesitate to eat almost anything from Saltwater raw. Having just return from a Saltwater culinary cooking cruise, I have had nothing but Fish and shellfish for the last 7 days. Pretty awesome trip, I can't wait for the next one.

And I rather enjoy restaurants with fish tanks, provided they are well kept and reasonably stocked.
