Personally, I love steel.

Indeed, not understanding and using the proper WPS for a given structure leads to many a sad weld.
I think the 6061 case is a good one to talk about because I think many people get the 'welding is terrible' from experiences with 6061 and not understanding the implications of removing the heat treatment.
And it is awfully hard to beat the weld-ability of steel. Difficulty working on it in the pits with hand tools, and relatively awful machining properties, are the reasons we don't use it often though.
