Strip connectors (choc blocks) and Wagos in Austria. Wagos have been around for more than 10 years I think, and at least in Germany many electricians believe that Wagos are far superior to strip connectors. (can't be overtorqued, don' mash the conductor, easier to install,...). Receptacles with screw terminals have almost disappeared here. Personally I don't like them. One reason is that it is virtually impossible to get the wires back out of some of these. For the second reason see the thread on the swiss receptacle...
Wirenuts do exist here, but they're awfully expensive and hardly ever used. ($10 for a 50 bag, only 1 standard size available)
