When I returned to cycling after a few decades absence (apart from being bewildered by all the drive train technology) I found the drops on my Galaxy were not as comfortable as I remembered.
I was very tempted to try butterfly bars (as a flat bar bike was comfortable - but only with bar ends) but could never decide how I would organise gear & brake levers.
In the end I never tried them, because I realised that the problem with my drops was one of width. A 45 cm bar(Nitto Randonneur) instead of the original 42 cm (Dawes-branded but Randonneur shape) and I was fine.
For me, the Randonneur shape is right on a tourer. Surprised they are not more popular/available.
I make a point of using the drops, not only downhill, but also into any headwind. It does help! And a change of position now and again helps with any shoulder issues or "saddle interface" problems. I wouldn't get that option with flat bars+bar ends, because I don't find holding the flat bar comfortable.
My fixed wheel now has an (even wider) bullhorn bar. That works for me too, as on the fixed I'm always on and off the saddle so that's a change of position in itself.
One day I might try a butterfly bar.... but I doubt I'll admit it on here
