The bottom line is that Linux tends to have better hardware support, especially for laptop hardware and power management.
When you run into problems, you'll usually have a much easier time finding vendor support or online community help for a Linux distribution than for FreeBSD.
Under the hood, FreeBSD is a lot simpler than Linux, and a lot of people like it for that reason. But if you want a generic Gnome/KDE/tiling WM/etc. desktop experience, and you don't need any BSD-specific features, I think Linux is the way to go. After all, we are talking about a replacement for MacOS here, which is pretty well integrated with the hardware and does not require a lot of tinkering to get working.
I've been playing around with various BSDs over the past couple of years, and I really want to like any of them enough to keep installed, but this is exactly the issue I've run into with freebsd and it's derivatives. On both my last laptop and the current one, I can get everything working to a fairly reasonable state, but there are minor but annoying hardware issues I just don't have to deal with in Linux.
In my most recent attempt (installing TrueOS on my spare SSD), some apps occasionally crash when I use the Intel video driver, so I'm forced to use scfb, which is a bit slower and doesn't render fonts as nicely. Additionally, the wifi tends to be a bit slower; I average around 4-5 MB (not Mb) down on Linux, but top out around 2 MB on TrueOS. I also have to use Firefox instead of Chromium on FreeBSD and its derivatives, as there always seem to be some bugs in the FreeBSD port; right now, it renders some bizarrely-shaped section of the window in a deep shade of yellow covering part of the URL bar and the top of the page, and signing in to Google to sync my extensions and history hasn't worked for like 10 major versions of Chromium.
I really like DragonflyBSD; it works a bit better for me out of the box than FreeBSD (I don't need to configure to not have the fan running at full blast all the time, and I've strangely had fewer issues with Chromium despite it using the same ports tree as FreeBSD with some custom patches), but I've had issues running any display manager other than Slim, and even that hasn't worked that well for me, as I've never been able to get the numlock and auto-login settings working (yes, I know, autologin is "insecure", but I always have FDE on my machines, so if someone can get past that, I don't think the login screen will stop them). Unfortunately I haven't been able to try it out lately; on my current laptop, BSDs weirdly seem to think that my screen resolution is 1024x768, and the only way I've found to fix that is by setting the GOP in EFI, which is not an option for DragonflyBSD currently. I've spent more time than I'm willing to admit trying to follow the manual EFI installation inductions I found on the DragonflyBSD mailing list; I think I got it to boot once, but apparently the snapshot I was using panicked when trying to load the specific wifi driver during startup (although I found out later it could load it fine after it was fully booted), and I've never gotten it to boot since, so I'm not convinced I wasn't mildly hallucinating or something. Every now and then the Dragonfly Digest will have some post talking about some new small step towards EFI support though, so I'm optimistic that someday soon I'll be able to boot it on my current laptop and discover a whole new set of reasons why I can't use it.
OpenBSD, on the other hand, works pretty great for me out of the box in terms of the GUI and hardware, but I'm not fond of the packaging system; I tend to like to have fairly recent versions of apps, so updates come a bit slowly compared to what I'm used to. Even worse, pkg_add is kind of horrifying to me compared to what you get on FreeBSD-based systems; for reasons I can't comprehend, it seems to query for updates individually for each package you have installed rather than first just getting a list of updated packages and then downloading the updates for the packages (if there are any). I'm unfortunately too spoiled to wait several minutes just to find out that there aren't actually any updates for my system.
I've never been able to get far into setting up NetBSD. A couple of years ago I got it installed but couldn't get Xorg to start up, and I've been unable to get the installer to boot on the most recent release; it prompts me to select the boot device from a number of options, and I've tried all of them, and none of them work. The issue seems to be fixed in the more recent snapshots, but I haven't been able to figure out how to install with FDE (I found the option to encrypt the disk, but it seems to be independent from the installation itself, and neither encrypting the disk before or after the installation seems to result in a bootable encrypted system), and I'm too stubborn to install it without.
NetBSD also gave me a bizarre halt-the-world problem on installation the first few times ("Old BPB too big") until I skipped the first sector.
I figure this laptop is old enough if it isn't supported by now it won't ever be.
