Not much difference, since you can find good deals and great locations in both. It will come down to usage. If you plan to rent it short-term for vacation purposes then Davenport will be better due to proximity to Disney. There is also more inventory to choose from that have pools. However depending on your price range, there are very nice communities in Kissimmee that are excellent for short-term rentals such as Terra Verde, Wyndham Palms, Emerald Island. So the bottom line answer comes to what is your price range and how close to Disney can you find a home within that price.
