My bikes are split, my fixed, which is my commuter and the bike I use the most is fitted with clips and straps, the clips have been straightened and rebent to take my steel toe capped boots, I like the fact that the clips and straps give me good foot retention and let me use any footwear I like. My verenti, which is my best bike is fitted with clipless, and I'm limited to cycle shoes when I use it, it gets used for Sunday rides and events. Of the two systems I prefer the clips and straps and I find very little difference between the two systems, I haven't used flats without foot retention on a regular basis for over twenty years and suspect it would take several rides to get comfortable with them.
