LVM-42W2 = 1080p monitor (no tv tuner)
2 DVI, 1 VGA, 1 HDMI, 2 components, 1 SVHS and 1 RCA inputs
TX-42F430S = 1080p TV
NO DVI inputs
I wouldn't call TX as better since LVM has a better CMO panel.
Westinghouse quality control is always YMMV - I have a 2yrs old near perfect LVM-42W2 and I consider myself Very Lucky
