The type of "communism" you accuse some people to be praising is probably rather the democratic and social system of the Scandinavian countries that works super well in Europe.
I don't know basically anyone actually saying UdSSR was good (except tankies but fuck them), because it was obviously not; it was a horrible and oppressive dictatorship. Funny enough, the only people I kind of hear this from are rather the people who actually lived in the DDR and say stuff like "Not everything was bad back there" and having it rather positive in their memory.
