Had a Panasonic 32 in 720p/1080i tv all last gen no problems. Really nice tv with low input lag. Online games were super smooth and everything. I've since brough both these TV's home and not sure which one to go with. One is pretty standard 39" 1080p 60 hz. Capable of the fake 120hz with motion on. The other one is 1080p 40 inch 120hz(240 cmr) with 3d enabled. I'm not sure I need 3d or 120hz. I messed around with it and it's nice to have the smoothing features though but seemed to have more problems with that tv too. possibly more input lag and the ps4 doing funky stuff at times. The picture did seem smoother though but could be my imagination. I am a nitpicker when it comes to ghosting and framerates. I hate that stuff but trying to keep it below $500. The 6030 is $499. The 5000 series is $369 so a pretty good price difference. $150 and the 5000 just doesn't have any bells and whistles.
These are the two best tvs I can find in my price range. Panasonic also has a 120 hz smart tv for $449 and sharp has a 42 inch 120hz tv for $429 without 3d or smart. I don't have any interest in a smart tv though and have read the Panasonic tv has issues with ghosting anyways. Done a lot of research. I just can't decide. The Samsung 5000 series seems to be the best for input lag and picture etc but it's 60hz. Just barebones.
