I am one of those heathens who feeds both raw and kibble. 
We moved to raw when our family was joined by a beautiful blonde greyhound with a very sensitive tum. We fiddled around with his food then he had a very bad attack of colitis and was very ill. We moved him onto raw and he never looked back - he gained weight, thrived and lived the rest of his days with us as a very happy contented dog, with a gorgeous coat, lovely firm poos etc. At the time we were a three hound family so it made sense to move all the dogs over to the same system. We installed a chest freezer in the garage, and all was well.
However, when we went away (not often) we'd take kibble with us for ease and convenience (though not for our sensitive boy) - don't think my MIL would appreciate having bits of raw tripe over her kitchen. Even though we were predominantly raw, we were never super evangelical about it and were/are quite happy to feed the odd Bonio, pigs ears etc. We found (sensitive dog aside) that all the dogs were quite happy to switch to kibble for a weekend, and though the poos weren't quite as small or firm as they are with raw, were fine.
Where we are now - our beautiful blonde boy passed away last year
and we are now a FOUR hound household. Quite simply, the economics of raw feeding for four were too difficult for us. It may be different when you have access to a really good local butcher, but we've moved to a compromise, also one of our dogs only has four teeth, so she was never going to be able to manage bones, etc.
Our dogs get Harringtons kibble for breakfast - the size of the bits is such that the dog w/o teeth just hoovers them up. In the evening, we get the frozen bags and like many raw feeders, feed a selection of things like tripe mince, beef chunks, chicken wings, etc. All the dogs also regularly get things like tinned sardines, leftover pasta, rice, veggies etc. We have no problems with poo (exploding or otherwise). If I won the lottery tomorrow, I'd def revert to a fully raw diet but we feel this is a compromise we can live with. Kibble is also great if we are away with the dogs - much easier.
All four dogs are looking really well, with gorgeous glossy coats, and nice poos. I take them to training classes regularly and the teacher always comments on how well they look and in a dog show last weekend, judge commended one's condition (all are veterans).
If you have a dog with a sensitive tum, and you find raw works for you (as it did for us) then I'd recommend sticking more rigidly to it. But if you've got a selection of gannets like we have at the moment, then your choice of food is dictated by what's best for your dog, bearing in mind cost and convenience.
