I have a Gigabyte M32Q (the 1440P version, the M32U being the 4K model) and I am very pleased with it's the 5th monitor I have bought in the last year or so (I have a bit of an unhealthy habbit with monitors
) and it's one of only 2 I still have. It really doesn't do anything wrong and gets everything mostly right, I don't think it quite offers as seamless a single overdrive experience as my older LG27GN850 and despite the fact it's newer and has a faster refresh rate on paper, I also don't think it's quite as good with motion (when I say quite, I mean a really small difference and it could even be down to perception due to the physcial size differrence). But, I do use it in place of the LG as my primary display, the reason is the colour gammut isn't as wide, but still wide, so to my eyes I like the presentation better than the over wide gammut LG presenting it's sunburnt flesh tones and such ...and although running the LG in SVGA mode sorts that out, it just loses a bit of pop compared to the 'inbetween' gammut of the Gigabyte. Also, I like 32 inches now, 1440P on it is a nice easy size for me to look at all day and it's large enough to offer a decently cinematic experience for gaming too (I have another gaming PC connected to a 55inch LG OLED in my living room if I really want that though).
The particular panel I have has very little backlight bleed, good uniformity and no dead pixels or subpixels but this could be different for another unit of course. Based on this I would quite happily buy the 4K version, infact in some ways I wish I had.
I was weighing up the merits of getting the 4K M32U around Black Friday, I got a good deal on M32Q at that time, the 4K model I could have also bought for twice as much, which actually wasn't really the issue, the reason I decided not to was the cost of entry for 4K is only part of the equation, the cost of maintenance to keep running the things I want at 4K the way I want is going to be high. Now as a hardware hobbiest I'm always buying and selling on stuff so that may not really be a big deal for me, I'm really not a person who buys computer stuff and then expects to spend nothing more on it for 4 or 5 years. But, given the current market for GPU's ...it's making me wonder about that a bit, hence the choice to stick with 1440P, even though I have been using high refresh 1440P since 2016 now starting with my Asus MG279. I do have a 3070 in my main system but the 8GB of VRAM on that and the lack of ability to buy higher end stuff for anything remotely reasonble is urking me. I actually don't typically expect to spend more on the GPU than any other part of the PC, I actually expect to spend the most on the monitor and tradtionally have done so.
Dare I say I think the Aorus FI32U is a bit pointless alongside the M32U ...unless you really want the Aorus styling. They do have nicer stands and build in general but there is nothing wrong with the none Aorus models, same panel and 95% of the same features.
If you look at the Ultrawide route, which I'm a big fan of and have also got one of, and have had 5 of over the years, pay more money and get an IPS one don't try and save by buying into the £400-£600 VA class ...the last one I bought was a short time ago which was the MSI Artymis 343 CQR, I have a lot of good things to say about that display, but ultimately it was still limited by the current state of VA technology in ways that annoyed me and they all will be, but it was the best effort yet on the (none 240Hz Samsung Odyssey VA front) ...also the most expensive though.
