I'd say it would come down to what your size preferences are....do you like your women smaller than you (Jazmin), or large as life and able to take a pounding (Julia)?  Both have excellent bodies, although Julia might be considered to have the better body because of her long legs.

Both are among the best in the business so you cannot go wrong with either one, so yours is a choice that is a win-win situation.

I lovelong legs.  I have a fetish for a girl dressed to impress.  A girl wearing a micro mini skirt either in leather or latex, fishnet stockings, and stiletto high heel pumps.
Corsets, garters, garterbelts, girdles, various nylon stockings, all kinds of high heels, leather, lace, and latex.

JULIA  No question Julia is a true GFE. Not to mention that fantastic body, great leggs and an ass to die for.

Both are great providers.  I'd lean towards Jazmin GFE; however, I doubt knowing my selection of ice cream would matter much if you went to Baskin & Robbins.  Whoever you pick will, I believe, provide a very nice session.

In the interests of balance and fair play, please remember that not a few of us will swear that an encounter with Jazmin is truly unforgettable.  She doesn't call herself "Jazmin GFE" for no reason.
