I use toe clips with slotted cleats for about 70% of my riding, platform pedals for about 20%, and Look clipless for maybe 10%. I really don't see any difference performance-wise between toe clips and slotted cleats and clipless, but the clipless are easier to enter and exit. I still prefer clips and slotted cleats because my 30+ year old Rivat slotted cleat shoes are still by far the most comfortable bike shoes I've used. When the Rivat shoes finally die I'll probably switch to clipless for most of my riding. I commute to work on a 3-speed so that accounts for the platform pedals. I don't feel any need for high-performance in that situation.
