Which one to buy: LG 23MP68VQ or LG 22MP67VQ

Both of the monitors are used. I can get LG 23MP68VQ for 130$ and the other one for 80$.
Which one to buy and why ?

Provided it works well, I suggest the LG 23MP68VQ as it has AMD freesync and is bigger. However, I should mention that the LG 22MP67VQ has better sharpness and at that price, is tempting. It depends on your budget.
