165Hz is better than 144Hz especially if you're gaming.
Any game that runs at 165Hz will be smoother than 144z.
If you can't spend much or are on a tight budget or prioritize other monitor features, a 144hz monitor is a fantastic option.
But if you have a powerful graphics card, and don't mind spending a bit more, a 165hz monitor might be the way to go.
240Hz and 360Hz monitors also exist but they require incredibly high-end hardware to run such high frame rates.
165Hz hits a nice balanced sweet spot for buttery smooth gaming without cost or performance overkill.
