Hi Brian,
I was making a generalization on longer strings. I agree, for example, when it comes to grands, a Pearl River GP213 will obviously never be a Steinway B, Baldwin SF10 or a Mason & Hamlin BB, due to inferior design, materials, craftsmanship, prep work, etc. But in a relative sense, the Pearl River 7' model should at least outshine its 5'3" brother due to the longer strings, everything else held constant. But would I trade my Baldwin L (6'3") for the Pearl River GP213 (7')? Nope, but I'd take the Baldwin SF10 in a second. I would also have to say in grands, that anyone investing in one less than 5'6" will usually be disappointed. In fact, once you get down to 5'2", several larger quality verticals would actually be better choices.
Similarly, I believe most would agree that given a quality brand of vertical piano, the taller one (longer strings, larger soundboard) will be superior to the spinet within that same brand. Is it your belief that in general one should go for a spinet rather than a console if those are the two choices?
