My new TN panel on DELL S2417DG looks better than my IPS on LG panel. So it's up to the model. Also, newer TN panels look really good and much closer to IPS than before.
And once you go high refresh rate, you can't go back.
I have 24" model which is 1440p 165Hz G-SYNC for quite cheap.
There's 27" version, also 1440p but 144Hz and G-SYNC. They're around 400-500 and they go frequently on sale.
