I wouldn’t dare purport to say X brand is better than Y brand, and don’t be fooled into thinking Pioneer are the best PDP, a stroll through their specific lines here will dispel that.

LCD has its issues with gaming that can sometimes overshadow the IR issue.
It’s your money, so read as much information as you can from reputable and non-bias reports, then make a personal decision on a TV for gaming.
