It is tempting, but the fact it's a 2-year old monitor that has be a bit concerned. The reviews are average also. Given the next 2560x1440 monitor OCUK sells is the Acer K272HUL at £320, which will be a newer model and panel... I'm still leaning more towards a 29" 21:9 myself. Just more of a 'wow' factor, albeit with a slight hit on the vertical resolution.
You are aware 1440P panel technology in these monitors is all from same era, Acer, AOC all the 1440P are using the same panels.

No difference!
Acer and AOC are also stock clearance deals at their prices, those too were originally £400+ screens.
1440P has not changed, the only new 1440P which has come recently is the TN based one with 144Hz in the Swift. LG/PLS 1440P is an old technology that came out like six years ago.
