I ride clipless and use the same shoes as ink1373.
I could wear them all day, without discomfort.
That said, I don't consider them as good as conventional shoes for all-purpose wear, such as going up and down stairs and walking on a variety of surfaces.

My son has excellent clipless shoes and yet has chosen to put clips on his geared road bike.
He straps in tight and must reach down with his hand in order to get his feet out of the straps.
A serious runner, he likes to ride and run in the same shoes.

I have no experience with clips.
I have had a bad fall or two with clipless pedals and shoes.
Since I ride through the winter, I have special concerns about falling on rutted roads, and so I have pedals with platforms on one side and clipless spd hardware on the other.
When I get on a bad surface, I clip out and flip over to the platforms.
As a system, it doesn't really work as well as I'd like it to work because I sometimes inadvertently clip back in to the wrong side.

Recently, I have tried riding my son's bike with clips, and because of my unfamiliarity with them, find it difficult to get my feet in and out of them.
I consider myself still in search of the perfect system.
