Taste being subjective all I could contribute is what are the best looking speakers to me.
I actually think the Thiel 2.7 speakers, which I now happily own, are about as close to "perfect" for speaker aesthetics as I can think of.They depart from the boring rectangle shape, yet aren’t a crazy, gauche design, but very sleek and contemporary with gorgeous wood finishes (mine being ebony). A really beautiful piece of furniture which IMO enhances a room.
I also really like the Joseph Audio Perspectives - just a bang-on combination of slender proportions that combined a modern-with-classic look with impeccable wood finish work.
Also love the Devore Fidelity O/96 speakers for a great combo of comfy-classic styling made contemporary.
