I initially used AACRAO (because they were cheaper than WES). Sent my documents by e-mail (scanned them in) on 1 Oct, thinking I was way early (deadlines 1, 15 Dec). Got a quick confirmation (looks automated) by e-mail that they received my documents. Then there was a long period of waiting and I e-mailed them several times - each time I was reassured that it was being done and would nearly be complete. I was about to give up on them so I e-mailed the uni I was applying to telling them of my plight (in advance of missing the deadline) and what step I was taking to resolve the situation - i.e. that I was going to use WES as well in case AACRAO didn't work out.
A few days after that, AACRAO confirmed that the had completed the evaluation and posted it out on 12 Nov. Felt relieved, but poorer. So far, my uni hasn't confirmed receiving the transcripts though ... (I'm hoping it's just because they are busy).
In the meantime, WES sends out an e-mail to me (16 Nov) saying that they cannot do the transcripts because what my uni sent was not detailed enough. I did MBBS - it's not the kind of degree that GPAs are calculated for. I replied immediately to [dr at wes.org] to tell them this (after confirming with my original uni that there is really no more detailed transcript available). I have, up to today, not heard from them - not even acknowledging my reply.
Once I get confirmation that the uni I'm applying to has received my AACRAO transcripts, I intend to ask for a refund from WES.
To be honest, I'm not sure if I'd recommend either - I was quite stressed out by AACRAO initially, but one thing they did do right - they replied my e-mail queries promptly, even though the reply did not sound convincingly reassuring. What I would recommend, for anyone applying in the next intake, is to sort out their foreign transcripts months - perhaps 6 months - in advance.
I'm sure this ordeal would turn off some good foreign applicants.

Applicants with Non-US Transcripts/Marks Sheets/Degree Conferral Documents
Applicants who will be submitting documentation from post-secondary institutions outside of the United States may choose to have their documents evaluated by an external credential evaluation agency.
While we recommend that applicants use World Education Services (www.wes.org), we do not require it.
Please note that evaluations from World Education Services will allow our reviewers to better understand the educational system in which you studied, which may be beneficial for your application review.
