Tom,

There is no right answer, it depends what YOU like the best. Personally, I like the LX9000. I like the user interface and find it easy to understand.. I tried a ClearNav a couple of times and couldn't figure it out. Did not seem intuitive to me like the LX menu structure. Windows vs MacIntosh

My recommendation is, since you have flown with the ClearNav to now spend some time flying with a 9000 and get a feel for the LX, then decide. If you can't find a glider to fly with the 9000, then download the simulator from the LX Nav site and try it out.
