Wondering if I should use a monitor or TV?

Hi guys, I'm buying a PS4 from being a PC gamer because I want to go a bit more casual.

I'm looking at the differences between a TV or a monitor. The monitor would have a lower refresh rate I'm guessing. Would this really matter? I do want to play FIFA 18 and I'm wondering if the lower refresh rate would make a big difference in a game like this.

I also heard some people say the TV has HDR and will have better graphics? What would be cheaper?

Any advice will help, thanks!
