Dont exist the best one. Depend what youre looking for. Type of circuit, street... for me the one you suit the most is the 3.46. A then you have the most iconic 4.44 the most expensive and rare one that everyone is looking for.
I've got a 3.0l compact and I've just put the 3.23 back in from a 3.73. The 3.23 gives you more legs but you've got to work a bit harder for it if that makes sense
