All my previous bikes along with whats in the garage now besides what I ride regularly, were steel.
Now I ride a aluminum with carbon rigid fork 29'er "hybrid" .......and its my best ride.
Either or..........It's all metal and I still like steel especially Salsa's like the ones shown above.....yet Alum with a carbon fork is sweet.
I never got into skinny , high psi tires, fast light road bikes........where one would see more difference perhaps...........and still don't like them be it flat or drop bar....

Touring bikes, MTB's, hybrid MTB's/Trekking, riser,flat or flared drop.....aluminum,steel frame, select carbon parts.....all the rest...... you can have
