Yes, all meat is equal.
Although I frankly doubt that your average human would taste that well or have good quality meat, for that matter. There's a reason most meat you eat has been grown for the sole reason of killing it for food. Right diet, right drugs and vitamins, right lifestyle and so on.
I have no moral problem with cannibalism. I can see why one might see it as a problem if it involves murder as a way of getting said human meat, but it doesn't have to. There are fresh corpses, for one thing. There are people who would willingly sacrifice themselves - I mean, that guy in Germany did find a volunteer.
Of course, considering that humans probably would taste like shit due to various life choices and wouldn't have much in terms of good quality meat (seriously. Compare human anatomy with, say, cow anatomy. Most good meat comes off the, well, butt and the thighs. Some ribs, too. And in case of humans, the average not overly built human specimen would probably only have sufficient muscle mass for a good steak on their thighs and ass.)
Overall, it just isn't worth it. I'm all for defiling corpses and shit (not in necro way, I just find the whole craze we have over death and burial idiotic. Person is dead, the body is nothing but fertilizer.) but there's little reason in cannibalism aside from novelty or, you know, the generic scenario of surviving while lost out in the sea with no food except for some random dude.
If I had a legal way of tasting it, I'd give it a taste the same way I'd taste any other exotic food. I'd gladly eat some raw seal meat, for example, just to know what it's like. I've tried a few exotic things before, like frogs and some insects.
Eating it obviously wouldn't bother me, although I'd probably stick with chicken because it would inevitable taste the same anyways. All meat is the same, and no matter how we live we end up as food for something, the circle of life and shit.
