Egg beaters are probably the easiest pedal type to get out of, you just kinda twist your foot past the float range and you're out, no extra force needed. . Pretty easy to get in, you don't have to worry about which side of the pedal is up. Sometimes can be a big tricky to get in by feel alone if the foot angle/position isn't quite right and there's not a ton of tactile feedback that you're aligned right.

Look Keo type pedals are the easiest to get into IMO, as long as you find the right side of the pedal. They're weighted to hang a certain way all the time, so it's not too big of a deal. Finding the right foot alignment to clip in by feel is the easiest due to the large cleat toe acting as a guide (I haven't tried Speedplays, so they might be better)

I would not recommend SPDs. They are the hardest to clip in by feel in my experience and offer no real advantages.
