Personnally I always felt that the steel is real mantra was just pure ignorance.
There are great bikes of very different materials.
I owned great bikes in steel, alu and carbon. My most comfortable and efficient road bike was made of carbon, the less comfortable made of crude 4130 steel tubing while some other steel bikes were really nice to ride but not as comfy as my current carbon bike. Reason is mostly because these bikes had that old school italian geometry with very short chainstays and couldn't accept tires bigger than 23mm.
I've seen steel bikes bent into unrepairability while I've seen carbon bikes shattered into several pieces then repaired and rebuild with very little difference in ride feeling after the repair for a tiny fraction of the cost a custom builder would ask to replace steel tubes on an existing high end steel frame.
