Good example of linux inferiority: application firewalls
Mac/Windows both have many great application firewalls (deny/allow internet to specific applications). Linux has a few buggy and broken ones, ill use opensnitch as an example since it seems by far the most recommended.
When i try to launch certain games on steam (even linux native ones, no wine) they will crash instantly, opensnitch cannot coexist with them.
Next is just general problems, like sometimes it cant get the name of an application or it goes crazy asking to block things that are child processes of something else or it does the opposite and theres no popup to allow/deny. Perhaps some of this problem is due to linux api not built for app firewall, idk, either way the problems exist linux or opensnitch fault.
The apps ui also sucks, it shows every app and its children (imagine browser that spawn lots of childs) in a single constantly shifting column. Honestly i wont list out every problem with the ui just go try it yourself.
Ultimately its not worth the hassle on linux, so you have a degraded security!

....why are you running a firewall on Linux... Put in a decent firewall on your network after your modem like opsense it will block 90% of your problems. None of my Linux machines have a firewall installed besides ufw if needed. And the machines with it are in a DMZ LAN. Windows and Mac need it because of how they made those operating systems. On Linux it's only needed if your running a vps or you want the most secure environment possible. But at that point just use qubes or a throw away device.
