Performance-wise, there really is much less difference than some people claim. But clipless is less hassle, because to get the full benefit of clips and straps you have to tighten the straps.

However, when just riding around rather than riding at race pace, you can get a reasonable degree of foot retention while leaving the straps looser, if you want. Certainly that is fine for rides on which you may have to stop and start frequently, in town for example.

Personally I use both. I go clipless on my road bikes but use clips on my singlespeed and, often, on my touring bike, because these are bikes I will often use in street clothes.
