Beethoven Quartets

Been repeatedly listening to Beethoven's string quartets lately, and it's really tough to choose between the 4 recordings I have (Vegh, Guarneri, Takacs, Emerson):

individual talent is exciting,
but team work is satisfying;
a gutsy tone keeps you on the edge of your seat,
but a nice intonation puts you to sleep in relaxation;
modern digital recording is crisp and clear,
but the old-world sound is warm and comforting...

I can see parallels between string quartets and marriages!
