Best 38" Ultrawide Monitor for Non-M1 2021 MBP

Ok, so I've put my 2 27" 4K LG monitors on a vertical stand, with the top one tilted down as far as possible and both monitors as low as possible. I had originally ordered another vertical dual monitor stand, but for 2 38" LG 38WN95C-W. The reviews looked good, but after digging I keep finding more negative and negative stuff.

I've never had a monitor with over 60Hz refresh rate, and I heard it changes lives bumping up to 120-144-244Hz, so I was really excited. But now I'm seeing things about inputs not working and yadda yadda yadda, cable issues, having to use a specific cable that isn't included with the monitor (the monitor states to only use the included cables) to use the "picture in picture" function, etc.

What are all of you ultrawide monitor people using with your 2021 MacBook Pros? I'm a hacker so I mainly just need the screen real estate and I also watch a lot of shows/movies at the computer, even though I have a 55" $3000 TV 2ft behind me :) I'll be running the MBP to the 38" ultrawide (whichever one I decide on) and 1 of the 27" monitors. The other 27" monitor will be reserved for my System76 laptop, as well as the PIP input of the ultrawide.

The LG 38WN95C-W got bad marks for color, lighting (blacks look grey), etc. but supposedly HDR looks good. Supposedly (the whole point of the monitor is to use TB3 from the MBP to the monitor for both charging and display) the monitor won't run over 75Hz with this method of connection, defeating the purpose of a 144Hz monitor with TB3 "do it all" connection. The only way to achieve 144Hz is USB-C to DP1.4.

Is anyone using a Dell or any other brand? My desk isn't big enough for a 49" + the 2 27" I have, with my UPS and two laptops and a lamp and enough space for everything else on it.

Sorry for the tl;dr post. I just reallllly want a good ultrawide to fit my needs. I'm extremely OCD and make use of my screen real estate efficiently. My workflow is superb. Any help would be greatly appreciated. Thanks for reading, and stay safe everyone!
