Thoughts on my monitor(s)

So I recently got my first PC. And I bought this https://a.co/d/025RixGV AOC Gaming Q27G4ZMN 27" Mini-LED Gaming Monitor, QHD Ultra Wide 1440p, 240Hz from Amazon as my main. I didn't realize until after that the reviews weren't so great on the one I have, But as a complete newbie It seems good so far. I'm looking to buy a second monitor today and know everybody says you should keep the same exact monitors. But I found this AOC Gaming Q27G41ZE 27 inch QHD IPS Gaming Monitor 2560x1440, 240Hz https://a.co/d/046u9ze5 that is cheaper than the first one and has a lot more positive reviews. Same size and brand. Just no mini led I believe. And a lot cheaper, I'm wondering what the real differences are between the two and which you guys think would be better for my main monitor vs 2nd. Or if I should look elsewhere for completely different monitor.
