Indies are better for me.  But maybe more difficult to find quality girl as indy.  But once you find, it is way better to deal directly with the girl...
I prefer from far a girl that is pretty, Full GFE and independant...  
I like knowing that the whole amount I pay goes to the girl and that she takes care herself of the room rental, (or receives at her place or a condo or appart...), the booking, paid advertising if she needs to...
Once in a while I find a young indy that does it all...  It is a lot easier for me to repeat with Indies...  To develop a relationship that goes beyond the SP/Client one...  They often becomes ATF...
Happened with Anna the famous indy CZech, Famous Mika, Alicia 32D (retired but one of my prefered one).
Lea Indy is a recent find that is fully independant and gives one of the best GFE session around.  Not yet an ATF because I have already a couple...
I also make ATF with agency, but usually, small agencies...
I will use Incall Agencies like GG once in a while but the repeat factor is lot less.  I saw Kate 3 times at GG.  I saw Mika 20 times... Anna, 12+ times...  And my actual atf 30+ time...
I don't see how I could achieve this repeat count with any MTL agencies...
Note that I do not meet much of the Indies that avertise on merb...  I only tried Alluring Aliyah Once...  over a year ago...
Why I don't go with Merb Indies? Price Range is out of my Limit most of the time and/or their age/size is also out of my limits
