Regulars vs. Randomized Players

Hi mates!
Considering the posts regarding the personal notes/highlights in the game it got me thinking to create the next opinion pool in this regard. With whom would you like to meet/play more/oftener in the game? Should they be regulars (already highlighted by you) or new randomized players (subject to highlight them)? Otherwise why do you collect this data about players - either for own game analysis or for opponents study?
Thank you for your thoughts.

I definitely prefer fresh fish to hardened sharks.

I don't use HUD and never will. The stats I take into account are based on some significant situational hands. I am not yet at the stake level to prove it but I believe that my dynamic system will beat even the best designed bot grinding programs out there because I can bluff and/or bait them and they will never out adapt me.
