Deciding between TVs

So I am replacing my TV ,but I am on a budget. So I have it lowered down to a few Vizios and wanted to ask the Giantbomb Community which would be the best option for playing games. I am also open to other brands but my budget is 600 dollars and my current TV is 50 inches so I would like to stay in the 47inches to 55inch range. Thanks for the help duders

Any help would be appreciated

I would like to help, but I'm not going to go through the trouble of entering a captcha to look at TV product information, what's up with that?

I'd go for the M-Series since it has a built in processor (for smart TV functions) and higher refresh rate (even though it doesn't matter for consoles).
Not sure if you care about that or not esp since consoles have just about the same services.
For an extra $70 why not.
The 50" and 55" E-Series are exact same thing besides the size.
For gaming the E-series would be fine.
M-Series would be better for movies and sports I'd assume.
It's your preference.

Here's a helpful http://www.displaylag.com/ tip. Search function is gone from that site for no reason currenty but it sorts results by displaylag so it's not too shabby. What's listed as "Great" is the E500AR Vizio and those displaylag times are great, going any better is something for the hardcore who are ready to spend heavily without stepping down many inches to use a 1ms computer monitor.
