The main difference is that the additional software you need to install doesn’t always come from the manufacturer on Linux. Other than that it’s actually pretty similar.
Heck, there are even devices that work better under Linux, such as the Logitech F710 gamepad. That one has been subtly incompatible with the USB stack of every Windows after 7 while it works with Linux just fine.
Usually between 1 and 2 GB/month, up to 10 in months where I travel, which happens about two or three times a year.
I have a plan which increases my data cap each year, giving me 30 GB currently. It’s 20 €/month, which is about average for a 5G plan of that size. I like not having to worry about my data usage.
Some of the criticisms definitely make sense. Parts of the premise are barely utilized. Some characters barely change at all. The finale makes a complete joke of one of the major threats in the setting. Janeway somehow manages to challenge Sisko for being the most liberal about Starfleet principles while simultaneously being a hardass when others do it. Neelix has screen time. (No offense to Ethan Phillips who did a wonderful job portraying him; the character just happens to be intensely annoying.)
I’m not going to list “the first episodes/seasons suck in comparison” as a downside; that’s a fairly common Trek ailment. People need time to nail those shows down.
On the plus side, it does make for a good space cozy and it takes the Trek ethos way more seriously than some newer shows. Some of the ideas it comes up with are genuinely cool. It has some of the better holodeck episodes. The Doctor is a better vehicle for exploring the rights of artificial sentiences than Data (The Measure of a Man notwithstanding). Seven of Nine was added as a mobile pair of tits and somehow ended up massively upgrading the show in terms of character development.
I’d say that out of the TNG/DS9/VOY/ENT quartet it’s definitely the second weakest but it’s not a bad show overall.
If you want to download once and then never have to deal with updates unless you want to, there’s always GOG.
(Also, yes, Steam is a lot more comfortable with a faster connection. I generally spend more time waiting for Vulkan shaders to be precompiled than for downloads to finish.)
