I always liked the Eleganza website, for the following reasons: representative pics (even though John does not take as many ass shots as I would like, something I have told him); user friendly; he posts a schedule every week so you know what days the girl you want to see is working; and a member's board which explains the service levels of all the ladies. The negatives are he does not really post much info on the ladies other than their nationality, age and measurements, preferring to let the pics speak for themselves, which in most cases they do. Some would also complain the Eleganza schedule is not helpful because the girls sometimes don't show up. I say to these critics, he has enough ladies working that usually you can develop 2 or 3 choices for a day, and if you do not have the foresight to have a plan B, then you are telling me you don't know what you are doing as a hobbyist. Your plan B and C need not be limited to this agency.
I think MSC is one other agency that does a good job explaining the service levels of its ladies, although the photography could be improved on their website.
I like the GOF website, and find it to be user friendly and informative with representative pics. My biggest problem with Devilish and GOF has always been that they don't post a weekly schedule on their website and don't take early day bookings like Eleganza does, instead posting a schedule on MERB at 6 or 7 pm every day. For many hobbyists this is no big deal, but I am not a late night guy and never have been, and I like to plan my hobby activities earlier in the day, usually for 6-9 pm. Fortunately, Chris has worked with me on this in the past when he is around, but if he is not around, I usually go with a different agency because I prefer early booking.
Martin of XXxtase, on the other hand, now posts a weekly schedule and he will also post the day shift ladies on his website, and usually the evening shift ladies are known by 3:30 - 4:00 p.m.
An example of an agency that had a 1st class website that never really lasted long term was Class XXX, run by the legendary/notorious "Mike." Dangerous Curves, another Chris agency production, had a website with great pics, enticing descriptions and loud, bombastic music (ditto with Platinum Escorts, yet another of Chris's many productions).
Allissa of Montreal was the last very successful Montreal agency that did not have pics on its website. An HDH agency that went out of business in about 2003, it relied heavily on enticing descriptions to market its ladies. This was of course the model of most escort agencies pre-Internet.
The best escort photography I have seen, by light years, is on the My Mademoiselle website. I have not met any of the MM ladies so I can't say how representative the pics are, but they are breathtaking.
I should note I have not been to Montreal since the end of last year so if any of the above has changed, my apologies.
