I mostly like it a lot early on; when he goes full-on serialist he starts to lose me (it's worth noting that by the latter half of the set where the late works are I was starting to get tired of it). I have no basis for comparison, unfortunately.
Mostly through a multi-year project of digitizing my LPs (now starting the various-composer discs at the end, plus 20-30 main-body ones I bought after starting). Unfortunately I'll have to go back to the beginning because of shoddy equipment through the first 2/3 of it, plus I've learned a lot about copying them.
It was quite a shock going from Weber to Webern in my vinyl rips.
