The VN247H-P is an exceptional monitor for casual & competitive gaming. It has an optimum size for viewing in FPS games, 1080p, 1ms response time, affordable, and ASUS has great support/warranty.
However, the VG248QE does have 144Hz which will result in more fluid motion, but 50/50 chance that will effect your result in better scores in games. Only way to determine this is to try one in real life because someone can tell you one thing, but that will just be their opinion.
I have both a Yamakasi Q270 60Hz and a Samsung S23A750D 120Hz monitor and can say I actually tend to get more kills on my 60Hz monitor for some reason. Everyone is different though and hope this helps.
Suggestion: Buy the VN247H-P and use the extra money on PC parts.
