I’m not such a fan of comparatives to rank things. But I find them useful to know your pros and cons, or at least to know how the surrounding community perceive your product. While having a coffee today I found this article on gis @ stackexchange: QGIS and gvSIG comparison. Made me happy than 2 out of 6 gvSIG pros are tools where I’m engaged: NavTable and OpenCADTools. Keep rocking cartolab and iCarto!
