Hmmm.....well I know there's one horrible piano that starts with a "B." Maybe it was Bechstein. Besides, Steinways are the best because they have what no other piano has--the tunable fourth string called an "aliquant." It adds so much to the richness. That's why performers all say you can get so much color out of a Steinway. With all Steinways patents (well over 100) all the good ideas are pretty much taken unless the company wants to pay royalties to Steinway. Essex and Boston are good pianos because they use Steinway patents. I plan to buy an Essex.
I did take a look at some Bosendorfers online, and personally, I would never buy a Bosendorfer because they have individually wrapped strings. They would never hold their tune, and if one breaks it's way harder to repair. Practical things matter just as much as sound IMO.

UV, before you buy that Essex, give the matter some thought and gain some piano culture, so that a sales person does not take advantage of you.
The aliquot strings, for example, are a Bluthner thing. The patent on those expired a long time ago, so the only reason other pianos don't have it (and Steinways don't) is 'cause the designer thinks they are better off without them.
You may be thinking of duplex scales, which in a reduced space have the same philosophy: string to vibrate sympathetically. Lots of pianos have it. In Faziolis it is indeed tunable. Plenty of good pianos don't have it.
Bechsteins are exceptionally good pianos. I am deeply fond of the old ones. The newer ones feel like Steinway clones to me, so I like them less, even though they are indeed very good.
There are a million reasons why not to like a Bose, but lack of craftmanship is not one of them. You may disagree with the design choices (I do) but no one seriously questions how impeccably well made those pianos are.
And now, just in jest, the only horrible pianos that start with B I know are Steinway model Bs. The other ones are all quite good. Baldwin, Bosendorfer, Bluthner, Bechstein ...
