Well, Ptss, I don't answer based on the assumption that here is only one answer, and only one brand. That's the all too common way for audiophile forum members, and forum members of all enthusiast products, it seems. "There is one right answer, and it's the one I own". Well, that's anti-reality, and anti-science. There is usually more than one way to apply science while working under the laws of science and engineering.
As for the particular brands I mentioned I heard, I've heard enough to know they have very nice promise. But without extensive A-B, I can't be unfair to those hard-working guys who have achieved something nice by shotgunning an answer that's fully researched, just to what, brag, that mine is the best?
And, the poster asked how do I compare, not how do I find the value.
My comparisons are based on ultimate performance, not value. I'm interested in the ultimate achievements first and foremost, not achievement per dollar. That does not mean I can afford the ultimate achievement. Whether I can or not is not the issue.
But, yes, I agree, there are some great JBL values out there, on very good, realistic speakers.
