I was in a similar situation and chose the Sharp. Had it for almost three weeks now and don't regret it one little bit.
Some pros off the top of my head, in no particular order:
- The screen is *not* highly reflective. Sort of semi-gloss at most. That's one of the biggest gripes I have with my LG 65LW6500, now in the living room where the screen is less annoying.
- Uniformity is pretty good for an edge-lit LCD/LED, mine is anyway. Again, better than my LG.
- Viewing angle is approx 45 degrees each way from dead center before you can detect any color washout. Good enough for my HT, and I was a little surprised, since some have commented on its poor viewing angles. Comparable to my LG's (IPS panel) viewing angles.
- Plays H.264 MKVs direct from external powered (ntfs formatted) hard drive just fine, and recognizes chapter timings.
- Can output AC3 5.1 surround over optical out. That setting is in System Options under Terminal Settings, not under Audio as you'd expect.
- Decent native contrast ratio (2,200 according to one test I read). Not to pick on LG so much, but my 65LW6500 has a native contrast ratio of 1,600. It makes a considerable difference.
- Motion interpolation (which I happen to like) is good, better than my LG.
- Can be finely calibrated. I don't think the Vizio has so full a range of controls, IIRC.
- The logo ( a lambda or inverted V) is at bottom center, not bright or obtrusive, and can be disabled. Useful though in knowing when the set is on and inputs inactive.
- It's big. You wouldn't think 5 extra inches would make much difference, but it does, to me. My viewing distance is ~ 8 feet in my home theater.
Pretty good set for the price. They're getting scarce though. Worse comes to worst, East Coast TVs could probably get one NIB for you. Mine was a display model with a steep markdown I picked up from Wal-Mart. Got a 3 year extended warranty at the Sharp website for less than $120 bucks (based on price paid).
Good luck whatever you get.
