wvr Finally someone with a different opinion on this forum, hope this can continue to be a civil discussion and an opportunity to learn more about both systems.
I currently use NetBSD as a daily driver on fairly modern hardware over OpenBSD. I have used OpenBSD as a daily driver and as my main web server in the past but later switched to NetBSD for reasons I'll discuss later down below.
wvr I honestly don't see a point in installing NetBSD over FreeBSD or Linux
I don't really see the point in bringing up Linux here. This is a BSD forum and since this is not a BSD vs Linux thread (which already have been discussed to death across the web) I'll refrain from going beyond here - we all here have our reasons to prefer BSD.
It seems to me that you don't have a lot of experience with NetBSD to be directly comparing it to FreeBSD which are two very different projects with different goals - but that is okay and I'm sure you are way more knowledgeable than me in regards to OpenBSD which I hope to learn more about.
NetBSD isn't very good at marketing. Their slogan "Of course it runs NetBSD" can me misleading and a very common misconception about NetBSD is that it only is an OS that you would use for exotic old hardware. Another misconception is due to it's portability and support for all kinds of different architectures means that it's comparison-wise a complex and bloated system - which in reality is the completely opposite. NetBSD seems to be very misunderstood and underplayed in the "suckless community", due to OpenBSD's favorable stance on security NetBSD gets thrown under the bus and people tend to neglect it's simple, clean design.
It's not about NetBSD supporting the most hardware, in fact Linux runs on way more hardware. The emphasize is on that NetBSD is a more portable OS due to it's simple design. Why? Strong focus on correct, clean code and the use of clear distinctions between machine-dependent and machine-independent code. NetBSD's focus on simplicity is what makes it portable.
I know you Mitch value simplicity since you are a suckless user and have been for a very long time. Simplicity alone is a valid reason to prefer NetBSD over FreeBSD so you should understand where I'm coming from. FreeBSD is not a simple system.
It's fair to argue that no modern OS is simple, but if you want a modern comparison-wise simple *nix OS - NetBSD or OpenBSD is usually the choice. Why Net over Open? While both systems have technical differences and different stances in regard to security and software simplicity, I wouldn't argue that neither is a "better" nor technical superior system and it usually boils down to use case and taste in software.
Another reason to prefer NetBSD is actual 1 tier support for ARM. While yes, OpenBSD and FreeBSD has partial ARM support, NetBSD is the only BSD which has proper ARM support.
So yes, there are reasons to run NetBSD on "modern" hardware in 2021 just as much there is a reason to run OpenBSD.
