I almost bought a Sharp Aquos over my Panasonic. In the end I went with Panny, but I felt the Sharp had impressive color. One thing to maybe consider, the display is quite bright. It would probably look better in a well lit room vs other displays. If your putting it into a dedicated home theatre, where you have good lighting control, it may be a bit bright. Also, see how it looks at off axis viewing.
In addition, it really is only a 1080p display. Sharp uses a split vertical pixel to emulate 4k. 4k displays are pricey now, making the Sharp look attractive, but once 4k displays start to drop in price?
Sharp has been around for years, great reliability. I personally feel the jump in refresh rate makes a difference. I play a lot of racing games on XBOX and my last display was 120hz. I saw a huge difference in picture clarity with fast motion games when played on a 240hz display.
This of course, translated into better picture during faster, action packed movie scenes as well.
I see by your signature, you already have a Sharp. The fact you're looking at another one speaks to your satisfaction with the brand, no?
That's my two cents. Happy shopping.
