In terms of reputation, both schools are on par with one another. Every industry/company is different in its focus on the pedigree of its executives. I think great companies do not place focus on where its executive went to school, but on the long term accomplishments of its executives.
For WEMBA, the biggest takeaway you will have is 1) from your peers, and 2) from the curriculum. Because of this, I would try to get an understanding of who may be your potential classmates. You can try to get in touch of some alumni from the WEBMA programs.
