In reply to wjcdean:
Topos vary quite a bit, those included with sport/trad routes are usually decent. Those included with high Alpine routes (Hochtouren) are okay at best and non-existent at worst.
So a pure rock route route like the Galengrat-Verschneidung will have a drawn topo which is okay but not as good as those in Plaisir Schweiz for example. While something like Aiguille de la Tsa will not have any topo at all, just a description.
I find the portal to be most suitable for use in combination with another source (Camptocamp, local guidebook, etc.), as it gives a very good overview of what is available in a certain area but lacks a bit of depth.
