I love bottling from a keg. One of my biggest pet peeves was having to pour my homebrew into a glass to avoid that yeast sediment in the bottles. Kegging gets rid of that. You also get a direct control over how much carbonation is added, over yeast carbonation, which is largely based on measuring out the sugar at the start and hoping that nothing unexpected will affect the yeast's ability to ferment.

However, the obvious drawback to kegging, for me, was the cost. It was of course expensive to get all of the equipment together to make the system work. I had to spend a couple hundred dollars buying a keg, gas canister, the appropriate lines to connect it all, as well as a bottle filler (I went with the beer gun too, and if you get it don't forget to buy the accessory kits. They have some important stuff: valves, disconnects, and other things you won't have to spare if this is your first keg.) and the accessories needed to make it all work.

Then there's the effort cost, which some people don't take into account. If you're like me, you didn't do much with gas lines before you got into kegging, and you'll have a bit of trial and error putting everything together and making sure it works properly. Eventually, you'll learn to tighten all of the gaskets to prevent leaking, and you'll get used to what connects to what. But it'll take maybe a day of playing with everything to get used to the setup. And, again if you're like me, you'll probably get a few cuts along the way.

Other than that, kegging is pretty sweet, and I think the beer feels more pleasant to drink when you can pull a bottle out of the fridge and drink it straight from there. But you have to be ready to cover the costs before you do it, and honestly the benefits may not be worth that to you yet. There's still nothing wrong with yeast-carbonated beer.
