Well, since
Karlo asked...

...(sort of)...
I enjoy a cobbled set of concertos above any of the complete sets.
For the 1st and 3rd concertos, it's
Janis for me, but I much prefer his earlier take of the 3rd with the more effusive and forceful
Munch. Dorati is too lean for me in the later remake of the 3rd.
For the 2nd, Richter has been mentioned but my favorite is
Weissenberg coupled with
Karajan, who does the music proud by providing true accompaniment rather than trying to dominate (probably hard to do with Weissenberg anyway!).
For the 4th,
Michelangeli is it, but from what I recall a later EMI remastering purportedly didn't make the grade which led to some murky sound (haven't heard it myself). I have the very first CD incarnation and the transfer here is dynamite, rich and clear (pictured below if anyone is curious).
