Sorry, no personal experience with my own ears. Multi-piece backs have been around for a lonnnng time. It was only a matter of time before tops started shipping with more than two pieces. The diff between 1-piece top (and how rare is that?!!!) and a two piece which has been the norm for eons is a non-issue, so I can't see a 3+ piece top being a
sonic deal breaker.
Aesthetics and people's attitudes are wholly different: witness the blowback Taylor got years ago when offering "streaked" ebony boards, and the usual suspects all derided it as a "marketing ploy" and obvious bow to using substandard materials above quality to maximize profit. Now look at who's offering "figured" ebony, LOL! Ain't perception grand!

Bottom line: if at all possible, play a guit and judge it for its
individual voice and playability,
not for its paper specs; no one hears paper. But if buying online, at least Taylor is unmatched in its consistency and QC so that may offer some semblance of confidence.
