both TN and IPS tech have their pros and cons! you asked for a gaming monitor so i expected that pixel response and input lag would be your first priority! although IPS and its variants are still good for most gamers at an 22-24'' range, at 27'' ghosting is inevitable so i would stick only with TN panels especially at ~250$ range.! if you arent that 'demanding' as a gamer the Samsung can still work for you.!
