I feel like everyone inherently has a number they're more comfortable with, e.g.60 ,70 ,80, 90 rpm. BUT, you can train yourself to practically any number. Starting my cycling journey in the '80s from a triathlon background, I tend to have a slower cadence than most bikies. And didn't get the memo for "compact" rings. I'm ok with having a slower cadence, in fact the only time I notice is when I ride with others.
I think the advantages of spinning out weigh mashing for sure: You're able to accelerate quicker, sprint better, sit while climbing easier, recover from a hard ride quicker. But I think the best examples are tour racers, the day in and out of hard riding requires quicker recovery something I'm not that concerned with as a daily rider.
So, to answer the OP, I pedal slowly coincidentally I ride slowly.
