I use toe clips and straps on all my bikes. They are more efficient than platforms because I can pull up, which really helps on climbs. I also like the fact that my feet can't accidentally slip off the pedals, especially when it's wet out.

20 years ago I used clipless on my road and mountain bikes. I had several low-speed crashes on and off road. I used Shimano SPD pedals and shoes, so I could at least walk normally, but it's still an expense I'm not willing to deal with now, especially since I have 10 bikes. No way am I putting clipless on all of them! Besides, I like not having to worry about those clipless crashes anymore.
