Shyee:

These are some of the things to look for when choosing/comparing evaluation bodies.
Requirements. Recently, WES decided to include O'Level for all evaluations.
Cost. To reduce cost some said you could use some online tools like hellofax to upload your documents to WES, I don't know of other evaluating bodies.
Time. To some, WES is the fastest in terms of evaluation, while some said they're all the same, when you consider the time taken to gather documents to send to WES. Some evaluation bodies don't resend documents to issuing institutions but they seemingly take time. According to this link by elfmannisback https://www.nairaland.com/4657743/canadian-express-entry-federal-skilled/17#70053234, ICES favors Master in Law.
Prejudice. Some say WES favour ND,HND, as two certificates, but Diploma in Nursing is not favoured. Some advised to use IQAS for Diploma in Nursing. Some think IQAS is also preferable for Law degrees. Also, ICES seem to offer the same evaluation as IQAS but faster.
Track Record. Some think WES has been in the business of evaluation for long, hence are more respected in the game. Some don't give mind to that. Meanwhile, whichever body you use for your evaluation, as long as it is approved by IRCC, IRCC Do NOT care. NOTE: Doctors and Pharmacists have their separate evaluation bodies.

I used WES for my two evaluations, though one is still pending, my reason for using WES in my examples.
To make decisions easy, maybe we could all share our experiences with our evaluations from different bodies, tag me, I would try to summarize it, then upload here.
Some links i gathered about ECA
