I started using the hosted version. One, because it was cheaper and two, because I needed something sooner than later and didn't have time to deploy and get it going. I confirmed that I can move the data out and host myself in the future.
I like it overall but some of the importing has proven to be flaky when grabbing csv files. Sometimes the header doesn't really apply and I will have to make a small adjustment and then reimport. I am still in the process of adding assets but I like it overall. I also use SpiceWorks reports and verify against known good data as I import the csvs.
