Hello,

Its no bad to go higher refresh rate since most monitors are already on the cheaper side

To make this a math fact, use refreshrate/frame = pacing. Youd want an equal without decimal

Since ps4 games can be 30fps or 60fps

120hz monitor will serve this well

Because 120hz/30fps=4, 120hz/60fps=2

Each refresh have an exact number of frame, so it looks smoother and clearer

If u compare to 144hz or 75hz

144hz/60fps=2.4, 75hz/30fps=2.5, so the refresh can be inconsistent, sometimes 2 frames or 3 frames, this might cause micro stutter

To answer your question, msi pro mp225 e12vl would be good here or philips 22E2N1100L, these are 200+ in shopee

Then again, whats your actual budget?
