Pola is facially prettier, Samantha has great knockers, both are great kissers, Samantha does better OWO imo, I would agree Pola is a tad mechanical but is a great actress. Samantha definitely gets into it more i would say... These days i swerve more towards Samantha but that's just me.
If you have the time, energy & resources then go for back to back appointments & see both... I am doing exactly that later this week
