Hopefully, this provides enough information to help you recommend a few alternatives.
You forgot to add monitor resolution (1080p, 1440p/2K, 4K) but budget alone doesn't make the list long.
Here are some options, where all monitors are 27", 144 Hz (or more), 1ms response time and VA panel.
1080p;

Only LG and Philips are flat, rest are curved.
Curvature actually makes reading stuff easier, since when sitting at proper distance, monitor curvature follows eye's view curvature. Also, curvature helps a bit to immerse in games (makes the game look more spatial).
27" is better with 1440p monitor than with 1080p monitor. Since depending on your sitting distance, you could see individual pixels on 27" screen with 1080p reso.
Higher refresh rate (144 Hz vs 60 Hz) doesn't remove stutters (that's GPU issue). But it does lessen/remove flickers and screen tearing (that is, if FPS is less than monitor refresh rate). But biggest impact is that high refresh rate makes movements smoother, without ghosting. This is especially noticeable in fast paced games (FPS, racing).
Response time is how fast monitor responds to your inputs. The lower it is - the less latency there is and overall experience (gaming) is smoother and snappier.
VESA mount is universal mount to fasten the monitor to monitor arm. E.g this one from Arctic,

I have a plan to buy the very same one i linked, but haven't got that far, yet.

There are 3x kinds of monitor panels: TN, VA and IPS. Actually there are more (variations of the main three) but i focus on these main ones.
TN panel is oldest of the three and also cheapest. Where TN panel excels is it's performance, most notably response time (1ms).
Though, TN panel also has it's downsides. Prominent ones are: poor color accuracy (washed out colors), very narrow view angle and poor contrast ratio (max 1000:1).
Gaming wise, TN panel monitor is best suited for fast-paced games (FPS, racing etc), where you don't care as much about pretty colors as you do about smoothness of movements.
IPS panel has been around for some time and is also the most expensive of the three.
Where IPS panel excels is it's color accuracy, which is the best of the three. Also, it has widest viewing angles of the three.
But where IPS panel falls short is response time. IPS technology by design can't be any faster than 4ms (compared to the 1ms most TN panels are). Another area where IPS panel falls short is it's poor contrast ratio which is equal to a TN panel (max 1000:1), despite it's great color accuracy. This is most prominent when looking at black image and where black isn't black but instead gray or some form of blue. Refresh rates aren't IPS panel strong side either and many IPS panels are 60Hz, especially on higher resolutions. There are some 1440p 165Hz and 4K 120Hz IPS panel monitors out there but they are few and far apart, also costing a fortune.
Gaming wise, IPS panel monitor is best suited for slow-paced games (RPG, strategy etc), where you have time to see all those pretty colors and where smoothness of movements isn't that important.
VA panel is the newest of the three and price wise, it falls between TN and IPS. VA panel was created to take the best of both worlds (TN and IPS) and combine them.
Where VA panel excels is it's contrast ratio (min 3000:1), where you'd see the deepest and richest blacks. Also, it doesn't fall short on other aspects as well. VA panel color accuracy isn't as good as it is for IPS panel but it's close to the levels of IPS panel (considerably better than TN panel). It's viewing angle is also a notch smaller than that of an IPS panel but again, considerably better than that of a TN panel. Refresh rate wise, VA panel is more capable on different resolutions than IPS panel. Response time is another area where VA panel does good. While VA panel can't naturally be any faster than 4ms (just like IPS panel), it can achieve the magical 1ms response thanks to the software solution in it.
With VA panel monitors making waves lately, there aren't any major downsides of them. Availability used to be issue but not anymore.
Gaming wise, VA panel monitor is suited for all kinds of games. VA panel is like Jack of all trades but master of none (except when it comes to contrast ratio, there, VA panel is king).
I am fairly sure my BenQ monitor is targeted for the photo editor.
Yeah, BenQ marketing does say that and while it does have IPS panel, it also has poor contrast ratio: 1000:1,

Now, i'm pretty sure that you haven't had VA panel monitor before, and thus have no idea how good of a contrast ratio they have. To put things into perspective, here's an example image about different contrast ratios;
Left - 3000:1
Right - 1000:1
Now, image on the right, when viewed alone, doesn't look that bad. But it doesn't look great either. While image on the left looks superb.
I also do quite a bit of image editing as my hobby and i used to have TN panel monitor. After i upgraded my monitor to VA panel (MSI Optix MAG241CR), i was stunned on how deep and rich all blacks were.
Sure, my new VA panel monitor is also curved, more than double the refresh rate (60 Hz -> 144 Hz), 1ms response time but to me, contrast ratio difference was biggest change. And my hobby of image editing became far better, since now i could tell far better about differences between different shades of gray.
I suggest that you read monitor reviews as well, before buying one. I narrowed the selection down for you (monitors listed above).
