Yes they can be. It depends as always, each person is different so there is no "best".
From personal experience since the 70's, it has taken me decades to find out that the way *MY* brain is wired, dome tweeters have always been more pleasant. I couldn't live long with piezo and horns.
But they sure looked bitchin! (language from the era when I started ...)
Of course equipment and sources driving them have to be taken into account.
For me it was a decades long road to discover that *on the whole - and just for me* generally I prefer domes. YMMV.
