Two sub-$150 1440p panels, and what you are actually giving up at that price.
Verdict
Both are 27 inch 1440p gaming panels at a price that was impossible a few years ago, and both are genuinely usable. The SANSUI runs a higher refresh rate and offers more inputs; the KTC is cheaper. Buy on which one is actually in stock at the price you saw, because at this tier panel lottery and unit variation matter more than the spec sheet difference.
1440p at 27 inches is the resolution and size most gaming advice converges on, and the price of entry has fallen a long way. What has not changed is that the corners cut to reach this price are in areas the specification sheet does not cover.

You want the higher refresh rate and more inputs. One hundred and eighty hertz against one hundred and forty four is a modest but real difference, and two DisplayPort inputs plus two HDMI is genuinely useful if you connect a PC and a console without a switch. At almost identical prices, the extra ports alone are a reasonable tiebreaker. Verify the exact model number when ordering, since budget brands frequently sell several similar panels under near identical names and the refresh rate and panel can differ between them.

It is cheaper on the day and 144Hz is enough. For most players the difference between 144 and 180 is far smaller than the difference between 60 and 144, and the money saved is real. FreeSync and G-Sync compatibility means variable refresh rate works with either graphics card, which matters more for smoothness than the peak number does. Check the stand and VESA support in the specific listing, because budget monitors vary and a screen you cannot mount on an arm is a limitation you notice every day.

Expect modest peak brightness, average factory colour accuracy, backlight uniformity that varies between individual units, and stands that tilt only. HDR badges at this tier are meaningless. Response time figures quoted as 1ms are best case measurements at an overdrive setting that may introduce visible overshoot, so try the lower overdrive modes rather than assuming maximum is best. None of that makes these bad monitors; it makes them monitors bought on price, and the honest expectation is a good SDR gaming screen rather than a colour accurate one.
It is the common recommendation because the pixel density is high enough that text is crisp without needing operating system scaling, and the resolution is achievable at high frame rates on mid-range hardware. 4K at 27 inches looks sharper but usually needs scaling and considerably more graphics power.
Less than the step from 60Hz did. The perceptual difference gets smaller as the numbers rise, and you only see it if your hardware sustains the frame rate. If your graphics card produces 110 frames per second in the games you play, neither panel's ceiling is the limit.
At budget prices, manufacturers source panels from several suppliers and quality control tolerances are wide, so two units of the same model can differ in backlight uniformity, colour and dead pixels. It is the main risk of buying at this tier. Buy from a seller with a straightforward return policy and check the screen properly within the return window.
Run a dead and stuck pixel test on solid colours, look at a full grey and a full black screen in a dark room for backlight bleed and clouding, check for visible overshoot on the overdrive settings, and confirm the refresh rate is actually set to maximum in the operating system, since many monitors default to 60Hz.
