Ummm....
Reasons why I prefer discrete components.
1) A designer should be familiar with discrete circuit disegn
techniques , something he/she loses when using integrated circuits.
2)You compromise circuit flexibility when you use an integrated
circuit
3)Discrete communication circuits are superior to integrated circuits
in performance.

I disagree.
Its a well known fact that MOS/FET are superior to BJT mixers.
Try reading something on that.
