The question really is which booker gives you the best service, and is most attentive to your needs.  Who do you get along best with?  

I've found that Adonia at TLC is the best currently around.  She's always given me good service, good prices, and has handled all my requests.  I also get along pretty well with her.

If you're going to use Adonia, a tip:  call her, don't email.  She'll respond faster.  And if you have any requirements, or a budget or anything like that, tell her up front - it'll make things go smoother.

If you want to PM me the ladies you're considering, I might be able to provide you with additional info.
