In their prime I'd say:

    1) Georgia Peach-I love blondes, the nice thickness and her willingness to do DP, gangbangs, and nice personality
    2) Lauren Phoenix-this is close, but I like tall girls too (I know strange contrast to Georgia who's only about 5'3") her smarts and also love of DP's and gangbangs (and her CIM is awesome too).
   
Other mentions/other loves-Gia Paloma, Audrey Hollander, Sasha Knox, Sara Jay, Alexis Golden, Haley Paige (RIP), Eva Angelina, Delilah Stone, Lisa Sparxxxx......you can tell it's hard to pick just two let alone 1.

It is nearly impossible to pick just one.  I first was introduced to porn by Ginger Lynn and she was my fav for many years.  In my mid 20's, Jill Kelly became my fav with a close 2nd to Asia Carrera.  Today, there are way to many hot ones.  However, Chanel Preston is my fav.  I met her and follow her on Twitter.  She is incredibly sexy, naughty, beautiful and intelligent.  She also takes the time to respond to several of my tweets.  Samantha Saint would be #2 with several honorable mentions.

I'm fickle.  It seems like every few weeks I get a new crush on a PS.  The latest would be Bonnie Rotten.  Before that Rachel Roxxx.  Before her Asa Akira.  Before her Annmarie Rios.  Before her Carmen Luvana.  And so it goes.  Every time I think I've found the ultimate, another one comes along.  Such is the nature of porn.
