We install Panasonic pro monitors, Sony pro monitors, Samsung TV's, Sharp TV's, LG TV's, and even Hisense TV's. These are the brands we offer because they typically have the best quality and don't have as many issues. We didn't start using Hisense until a couple years ago, we opened their tv's and saw that they sourced their panels from Sharp and backlighting from phillips. They are typically cheaper in cost but we haven't had complaints yet. If you can find one with a good warranty, I wouldn't hesitate. If you're concerned about brand name, then go for something else.
With that being said, I wouldn't worry a ton about refresh rate. 60hz is like I said, what is typically used. If you play video games (ps3, 360, xbox 1, and ps4) can only produce a 60hz refresh rate, you may see artifacting if you are trying to run it higher. However, every tv I've setup has the option to turn off (motionblur, clearpic, etc.) the 120+hz and drop down to 60. Some even let you pick between several. It's mostly a personal preference.
Sports benefit because of the added frame interpretation; In football it will add frames in between giving it a smooth picture quality.
Look somewhere like Tigerdirect, newegg, etc. I've ordered many times with no problem.
