I have been using various Debian-flavored Linux variets for several years in both desktop and server.
Recently I got a System76 laptop for work because they are food quality, repairable, and mostly “just work”. The main issue I have run into is Cisco Secure Client (formerly AnyConnect) simply breaks in Ubuntu/PoP. If I do get it to install by ignoring Cisco’s shitty instructions, it either won’t route traffic once connected or corrupt itself attempting to auto-update.
It is purely a Cisco issue because they don’t put much effort into their Linux VPN software. Other VPNs not only work easily, but can also integrate into PoP Cosmic. Cisco and their restrictive nature just make the process impossible.
Heck, you can’t even download their VPN software without a Cisco contract. So if my company doesn’t provide the correct version or distro package, there is no way for me to get it. Since most people on the helpdesk don’t know anything about Linux, they simply provide the generic Linux.tar.gz file instead of the DEB or RPM files.
I gave up and installed Windows on a second NVMe.
Not sure if it is open source, but I switched to ReoLink a while back and have been very happy with it. Good Home Assistant integration, no subscription, and everything can be local (store video clips to an onboard SD Card).
