I have a different type of pedal on every bike.
Road bike (Trek 1100): Speedplay Zero
Casual fixed gear (Surly Steamroller): MTB platforms with plastic cages and straps
City/commuter 3-speed (Takara road bike conversion): Big, plastic platforms
Track bike (MASH Parallax): Shimano 105 SPD-SL
New-to-me SS gravel bike (All City Nature Boy): Shimano PD-530 and compatible shoes are on their way, should arrive tomorrow!
I feel pedals are like handlebars, in that each design offers advantages and drawbacks for a given use. Cycling happiness depends on matching your component selections to your riding style. If they ever come up with one pedal that gives outstanding service for every type of ride, I'll buy a half dozen pair and put them on every bike. That's not going to happen though.
