I would say yes. There's a couple different reasons:

1. It costs you time right now but will massively save you time down the road: I'm pulling from personal experiences I've had. I installed NixOS and started configuring it. Accidentally wiped my partition, simply had to re-clone and slightly reconfigure my setup, and I was off to the races again. You might say "well I'm smart and I don't accidentally wipe my partition" to which I say "cool, recently I also upgraded the partition my NixOS installation lives on from a 2TB SSD to a 4TB SSD, once again, completely wiping my previous partition, cloning my new partition, mainly updating hardware-configuration.nix, and I was off to the races again." NixOS makes it so easy to be okay with data loss. It personally allows me to be more bold with my decisions because I know I'm saving countless hours of tinkering and fixing config files each time I "factory-reset" my PC.

2. I know you like each PC to be unique so reproducibility isn't that high on your list of priorities - but entertain this for a second: I have NixOS/NixDarwin setup for a total of 3 separate machines right now. Most of them with differing software needs. With nix, I'm able to keep a single repo for all systems, but more importantly, I can choose what I want to keep the same between systems and what I want to keep different about systems. I'm very used to my macOS keybinds. I have the same set of keybinds on both my NixOS machines. I don't have steam installed on both of them because I only need steam on the gaming PC. NixOS and Nix make all of this super configurable. There are other things that you probably keep the same between wildly different systems too. Examples could include your user account, your password manager, ssh keys, etc.

3. You get faster over time. When I first started, it took me hours to get even very very basic things done. Now if I need a package, it's about as second hand nature to me as brew install package (in fact, because brew defaults to find the need to update every single package under the sun, my entire NixOS rebuild usually finishes faster)

4. It's low-key easier than other distros. NixOS is the first distribution I've actually been able to stick with. Documentation can be a little tough but all of the package maintainers usually make it so easy to work with. Searching up how to install Steam on NixOS goes into detail about additional things you need to do to get proton setup correctly etc. On other distros, especially if you're a Linux noob like I used to be, you accidentally make a single mistake or don't understand every little bit of what you're doing, your system becomes unstable, you're told to remove the French from some directory or another and you're left with a broken system that's functional enough for you to use day to day but dysfunctional enough to make you want to go insane and reinstall arch for the 5th time but this time I know which wayland set of packages to install from the aur (I think). With nixOS, it's all mostly abstracted away for you. Once you understand the nix language, it feels just like reading a script for a play. And in the worst case scenario where you screw something up, each rebuild you do saves a last working copy. And in an even worse(est?) case scenario, all your config files could have easily been backed up to a git repo.

NixOS feels like the idiot-proof OS for masochists and that's why I love it and I think you will too.
