It's like Night vs. Day.

You probably won't go back. Even for 'social' rides I end up riding with clipless, and, if necessary or useful, changing shoes when I get there - but usually not necessary as a lot of the folks I roll with also ride clipless these days. These situations tend to be for formal events, hiking/mountain climbing, soccer, or some sport event where I'm going to need sneaks...
We're all wearing MTB shoes (and our various choices of pedals systems to accommodate two-hole soles), so walking has never been an issue
