"... Hans Kmoch’s Pawn Power in Chess is considered a classic by many. Nonetheless, most people found it daunting and confusing, given its weird terminology. Also the scope the book was more theoretical than practical; not an easy book to read and study with. ..."

This sounds like what most people would have to say about my college electrical engineering and especially mathematics text books. It's a good thing I ignored the viewpoint of most people, else I would probably never have achieved my engineering degree...
If you let most people determine your path in life, you might never achieve your potential...
I have never seen a mathematics text book with weird terminology - they all use a standard one.
Judging by reviews most people think that Kmoch's book is good. So I just follow your advice and don't let most people's opinion to determine my path.
The following is representative of the kind of mathematics to be found in university level advanced engineering and physics text books. What would most people think about it? weird? incomprehensible? jibberish? Of course, if one has an advanced degree in any of these subjects, then for them it would simply be standard mathematics terminology...

The point being the level of sophistication of the student with regard to the knowledge base required to understand the material in question. If one hasn't attained a prerequisite knowledge base, one is likely to have significant difficulties when studying and understanding the more advanced material of a technical subject. So it is with the more advanced chess books.
Quote from kindaspongey obviously talks about chess players opinion about Kmoch's book. You are asking about general public opinion about math books. To me it's comparing apples to oranges.
The most advanced chess book I've had a look at was probably Dvoretsky's Analytical Manual. It's intended audience is well over 2000. It's hard as hell but it's written excellently and fun to read.
Advanced material can be explained clearly (Dvoretsky in chess, Feynman in physics) or it can be made obscure (Kmoch). In the latter case half of the time you spend struggling against the author's inability to explain things.
Some people like the book and some don't. What more is there to say?
That's what it boils down to...
But one will only benefit by serious study of the book...
As the adage goes...."you can lead a horse to water, but you can't make him drink."
