I've fed my dogs raw for over a year now, and I can't recommend it enough.
There are other factors that have made me very happy - their teeth, their poo's (sorry but firmer and there's a whole lot less of it too!), their coats, they have nothing at all medically wrong with them (touch wood), - but the very biggest one that would not get me to switch back to kibble is that my dogs are happy! You can see their excitement over their raw food, they munch and take time to enjoy, rather than inhale it, and they are just happy little souls! Happy not overly hyper!
I don't have one single drawback or negative thing to say about raw. At all.
Storage space - I bought an extra freezer just for the dogs.
Cost - found it be no different, if anything it's a little cheaper, depending on what meats I get them. My farm shop gives away a lot of bones and trotters etc for free, rabbit is expensive here and I so wish I lived more in the countryside where it appears to be cheaper, but not to worry it just means they have it once a week rather than everyday.
Time consuming - how?! If its frozen I take it out the freezer the night before ready for the next day. There's no weighing out of kibble portions, no tipping out a kibble bag into a water tight sealed container to stop it going soggy or mouldy... The most I have to do is chop something up or open a can of tuna!
Messy... Nope. The dogs eat in the kitchen or hall. The only time they get a bowl is when it's offal or with an egg... if it's something particularly messy I leave it not completely defrosted so that it's less of a mess, but y'know even if they make a bit of a mess with something it all cleans

it's only like the mess a kid can make...
I love my dogs... I wish that I had known the benefits of raw years ago when I had my old dog Charlie, I truly believe he would have been so much better off with a natural diet... But at least I know now and I would never feed a dog anything but raw.. no more dog treats from supermarkets, no more tinned sloppy dog food, no more artificial junk...
Just my opinion...
ps am I being daft, but of course you wouldn't feed potatoes or rice raw or probably vegetables without cooking, but why would you feed a dog these in the first place?! My dogs don't get veggies or rice...?!
