E32 has more off road detail which by most reports are pretty accurate. It has more trails than bicimapas. By the way, with E32, "Brecha" means dirt road, "Verada" means trail.
E32 does not auto route and Bicimapas does, if that's important to you.
I have both maps but have not done enough comparisons to recommend one over the other. Both providers are putting out updates every year, so the support is good.
