amd freesync, 240hz, 27-inch, input delay is my greatest concern, this would be the right choice?

Other cheaper Acer 240hz 27" - XF270HA - has bad frameskipping.
You can try, but be ready that this can also have a major flaw.

It have HDR on HDMI(cap at 120hz)
And have blur reduction (call as MPRT at OSD)
You can turn it on in 240hz

But you can not turn on HDR and MPRT at same time

Can you provide pictures of OSD (MPRT) and provide pictures of http://testufo.com/crosstalk at 120, 144, 240hz with MPRT enabled?
There's no such option stated on Acer's site for this model. Also there's no downloadable user manual. It may be undocumented feature, but since that monitor is affordable one, its interesting to do these tests.
Also can you check it for frameskipping at 240hz http://testufo.com/frameskipping , because other Acer XF270HA has confirmed frameskipping at 240hz (and it is a major problem).

I don't own the monitors ,But I recommend to a lot people in Taiwanese forum
according to their report the MPRT did turn the monitor darker and make the UFO eyes clear
You can see that MPRT on OSD on this website GIF

The price is really low 144hz TN (kg271B 320$ kg271C 255$) and have MPRT with OD also have crosshair
But I got a report is about Kg271C have Inductive sound on power button

And KG251 QAbmidpx (selling in japen) have bad input lag (1~2 fps slower than 60hz monitor)

Also I have tools to measure input lag and color volume with color gamut coverage
But the manufacturer(only MSI and Acer replay me) say I'm a "user" no such "service" for me ):

There are two gifs with OSD settings.
Setting named MPRT is seen only for 144hz model (with buttons on front side)
240hz model have back side buttons and there's no MPRT option shown.
