Info Poll: Blue Gems or ST to fulfill your PV needs?

has anyone used both as of recent....or just one? who's is ya favorite girl at each?
The question comes up ever so often in my thoughts...so why not take a poll? I'm a ST connoisseur in my mind and would like to know where the masses stand on this issue.  

 
Eden seems like they switch cast every 2 weeks from looking at the website alone....so I won't even mention them, lol.  

PM's are encouraged. My VIP is reloaded.
