I used to like only taller faced drivers but now it doesn't matter to me.
In my experience, I find the longer heel-toe heads need a stiffer tip to help square them up is the biggest difference in the two. My miss is up and down but I don't tee it up too much either, so small faced drivers are good too.
I actually like the smaller heads just as much. (SMT Spectrum, 02 for eg)
As for irons, I have played small heads my whole life, so giant ass irons are a no go.
I currently play Snake Eyes 600xc and I think they could double as snow shovels .
