My first ride on a new bike with toe clips about 18 years ago - came to the first stop, forgot I had toe clips and just toppled over. Never did it again.

With clipless pedals I've fallen once when I started too slowly and leaned over too far to the wrong side. Hasn't happened again (yet!!!).

I have one bike with SPDs - they are very easy to get in and out of. All of my other bikes have Speedplays - I would never have any other type of pedal. Super easy to get in and out - mine are the light action ones. I've also tried Shimano SPD-SLs (105) and found them okay but I didn't like that I had to look down to get into them. With practice I think this would change but Speedplays are double sided so I never have that problem.

They are also really easy on the knees - my partner had a knee reconstruction about 6 years ago and used to get some knee pain when cycling with Shimano SPD-SLs. When he switched to Speedplay he found that the knee pain disappeared.
