Ken, I mostly smoke the fish I keep. I have grilled/baked them too. Not terrible, but I prefer local trout for sure.
If you catch them early before they're all banged up and zombified it's better. Makes me gag when I see guys walking with fish on a rope that are already rotting though.
All the flesh is white not the traditional "pink", though many people don't realize the farmed Atlantics they buy woud be the same without the color added.
People come from all over to catch and keep them...Lots of guys from CT, OH, PA, NJ. We had 2 guys at the camp last year theat drove from Alabama.
The snagging thing is all BS. The fish really don't feed when they make the run. If they weren't harrassed from the minute then enter the river, they might bite out of instinct or to kill the eggs of other fish, but not likely here in NY. Everyone is snagging the fish, it's all in the "technique" used. Exaggerated or repeated jerking of the rod will get you a ticket.
Some of the fish do spawn successfully. More and more studies show some natural recruitment, but they also swim to the hatchery in Altmar where they collect eggs and raise the next batch of stockies.
