Real instruments get played in a huge variety of fashions...

Just as there are great arranger players and not so great arranger players, and a great player on a less than great arranger is usually a happy listening experience, whereas the less than great player can make the best arranger sound awful, there are great real instrument players and not so great...

Sad thing is, basically, if you base your arranger expectations on listening to the BEST players playing the best acoustic instruments, you are ALWAYS going to be disappointed! And only working hard on your PLAYING, as opposed to agonizing over which arranger you play is going to have any significant chance of increasing your contentment with how you sound.

If you can't phrase a sax solo JUST like a sax player, having the 'best' sax sound is not going to help one tiny bit!
