I have been asked to compare "officially" some pentest certifications, namely:
Now, I have my points of view and I don't want to be biased by them, hence I would like to ask you if you have some references to benchmarks or comments around the network. And yes, I know Google's a friend, but people's mind works somehow better. Especially, considering that this is a heavily "sponsored" topic.
Really haven't too much experience with most of them but my two cents:
GIAC - has a lot of certifications, lets you specialice on what is most relevant and dig deeper into that topic so if i.e. you are working on pentesting web-applicaitons or wiriting secure web-applications they should be great.
CEH - Covers a lot of ground in the same certification as far as I know. So demonstrates general overall security competence.
As for the other two you mention I have no in-depth knowledge so I refrain from commenting. You could also take a look into the general ISACA certifications CISSP/CISA but they are really not pen-testing. So my advice is either specialise or go with the most fitting GIAC/SANS certification/training. I went with GIAC after some consideration.
