With all due respect, man, what was buggy about 1720? I'm still using it on my Z690 TUF Gaming D4 with no issues of any kind. A year ago, when I got 2004 and then never versions, I've experienced insane BSOD issues and ended up having to replace my motherboard. IDK, I'm leaving mine on 1720 for the rest of its life. Z690 formula bios 2703 - Republic of Gamers Forum - 960305 (asus.com) I posted a short version of my experience here.
I never used 1720 myself, I just remember a lot of people complaining about it. If it's working well for you and you want to stay on that version, that's all good. The most recent BIOS, 2703 has received pretty good feedback though, if you ever do decide to upgrade.
