Monitor Question

I'm running Studio 17.1.1 on an M1 Mac Mini 8GB (OS Big Sur 11.2.1) that has dual monitors: hp 27er via HDMI and the MSi MAG274R 144Mhz. Both are 17" IPS monitors.
I'm planning on replacing the hp monitor with something else. Should I go with a matched pair and get a second MAG274R? Or should I get something else? I've heard that it's sometimes better to use two different monitors because each one shows colors differently (is this a consideration?). One option is the get the MSi MAG274QRF-QD - which has a faster refresh rate of 165MHz - they say faster is good for gaming but not so important for editing (I do not have interest in using this setup for gaming).
Any thoughts or suggestions? I'd like to keep the budget under $500. Thanks!
