The first two looked very interesting but I only bought the last one when I was in Israel in Netivot.
But none of them did i ever make a major point to study.
I should perhaps mention that the books about philosophy of the Rambam are not leaned in yeshivas in general. The reason is that traditional yeshivas learn Talmud --Gemara rashi and Tosphot. it took a major battle in the Lithuanian yeshiva would to even introduce Musar which are books devoted to self improvement of ones character.
Philosophy of Torah books simply had no place in the curriculum.
I know that many people think that Jewish philosophy and theology are known and studied by rabbis but this is simply not the case.
And when you get involved in the world of chasidut the tables are tuned complete over the rambam.
The general principles of belief in chasidut tend to be based on the Zohar. The Rambam is used to give a cloak of respectability but the actual world view of chasidut is highly anti Rambam.
