any list of transistors best suited for certain ghz bands oscillators and LNAs?

[Terminator3]

does such thing exists? i think it must be based on s parameters, stability circles, etc.

You do not indicate your frequency of interest. Best LNAs and good VCOs are now offered as MMICs. Check Hittire, RFMW and Mini-Circuits for good choices.

NEC68830 is used for 1-2GHz VCOs in many papers and App.Notes.But the same transistor is also used for LNA or Mixer.
So, it's hard to say there is a such list.Every transistor-of course except some extras- can almost be used for all purpose with diffeent design techniques.
