Television technology advances, so if they're just replacing "like" without any kind of inflation for relativity, the PN6500 should perform better than your old TV in most areas. One exception I can think of that may justify an F8500 would be if your old TV performed well under glare. I could be wrong, so don't quote me on it, but I don't think any plasmas from Samsung and LG but the F8500 perform well under glare. Many plasmas are like mirrors and some are only watchable in a cave.
Did your old Fujitsu have the two optional speakers? Most new TVs with internal speakers built in have terrible sound. One Amazon reviewer says the sound on the PN6500 is "near worthless"
Black levels are better on Samsung plasmas than LGs. I don't know if the PN6500 would be much better than your Fujitsu in that area.
