I have a set of clipless and a second set of platforms. I swap them depending on what I'll be doing. A placid roundabout with family? Platforms A quick run to groceries or local roundabout? Platforms. 15-25 mile solo training? Clipless. Weekend run with friends? Clipless. I don't track exact times but I feel that I use 80% platforms and 20% clipless.
Having a second set of pedals is not so expensive and many would not agree but as told previously here, clipless worth if you're doing a long ride and/or not short runs. Some people are full of them if they insist on wearing clipless for a city ride and going from light to light.
What happens me sometimes is that forget when I use clipless ones and had my own fair share of stupid fallings on a stop sign
