I use a mix of pedals
I have a pair of this type (wellgo/performance) (spd on one side/platform on the other) for a bike that I use for commuting (some times) and also to just jump on for errands and such on weekends. works well and if I miss the spd side when trying to clip in, like after a light, it is no problem use use the platform side to keep going and then clip in, so easy and pretty efficient
yesterday I got passed (not that hard to do) on the commute by a guy on a really high end carbon colnago. He was in full kit and using spd/platform pedals.
I also use spd and spd-SL I commute mostly on my nicest bike and use spd for commuting as it is a bit easier to clip in and the shoes are better for walking When I get chance to go for long rides on the weekend I switch to spd-sl
