IT workers desperately need to unionize. There is so much bullshit that happens, folks are expected to do three different roles at once, have multiple technical stacks they are experts in, and work extra hours + be on call after hours or on weekends.
Performance and how configurable things are, plus ease of use.
For instance, my default router/modem device from my ISP was super clunky and confusing. I needed to set up some custom port forwarding and firewall rules. The aftermarket router I bought was faster, had way better wireless coverage, and the UI was so much easier to set up the configs I needed.
So it’s up to you, from what you said, seems like you probably would be good with the default from your ISP.
