This depends very much on the chicken. If you get good quality chicken breasts (ideally skin on) then they can be very tasty with just some brining and a pinch of salt and pepper.
And whatever you do, don't overcook the chicken breasts as they are much more sensitive to overcooking than other parts of the chicken. Many people cook their chicken breasts to an internal temperature of over 72 deg c (165 F), which can really dry out the chicken, when really don't want to go much over 65 c (150 F).
I am absolutely overlooking by your standards as I prefer it all stewed for about 16 hours! I don’t enjoy the broth cooked longer than 36 hours.
Grilling and other methods of preparation would be totally different. I’m mainly speaking of soups.
> Instead of tasting flavorless and washed out, the chicken breast produced the cleanest-tasting stock, with the most intense chicken flavor. But it also produced the thinnest stock in terms of body.
> The thigh meat also produced a light-colored stock, but it had a muddier, less clean flavor than the breast stock.
> The wings produced the stock with the most body, which makes sense, given the number of cartilage-rich joints in each wing. But the flavor was also not as chicken-y as that of the breast stock.
> Bones also made a stock with a less distinct chicken flavor, but they contributed some bass notes that were pleasant.
> The whole chicken produced a middle-of-the-road stock: not as tasty as the chicken breast stock, but not as muddy as some of the others.

I read some articles like this when I started out making bone broth. Wing broth is this way, thighs are another, they said, etcetera. Since my goal was bone broth I didn’t consider boneless breasts - turkey breasts are great, though. Since my goal was health and allergy avoidance, I went for whole chickens as they’re my ally processed.
I’m mainly now basing my analysis on plucking parts of that whole chicken at different times. Sometimes when I’m hungry I’ve bought a breast or two, boiled it, and compared to the normal stew I make, it was rather flavorless. I haven’t tried extended simmering, I admit.
Surely this is opinion-based, but my belief is that making soups or saucey dishes from chopped up chicken breast with no bones is much less rich than from a whole chicken stewed overnight. Countless grandmothers through history would likely agree.
It's fairly cheap, so it's the default for overcooked, dried-out protein. And sure, lots of things can be a substitute for that.
Industrially-raised chicken: Bred for extreme fast growth. Slaughtered young. Fed on straight grain. Bland flavour.
Old-world chicken: Grow at a more "natural" pace. Slaughtered when mature. Permitted to forage and eat various food scraps. Rich flavour.
I don't have a weak stomach, almost nothing makes me feel sick, but that did it to me every time.
