If an ePub is also available from B&N and Sony, then it almost certainly has been provided by the publisher to all three ebook sites. So the advantage of the Google store is that they are matching Amazon prices. I have bought a couple of ePubs from Google and the DRM is standard Adobe (e.g. you get a .acsm file for import to ADE). The ebooks I bought appeared to be standard ePubs from the publisher.
Amazon and convert also works well, just avoid the TOPAZ ebooks (they don't list the filesize on their Kindle Store web page).
