I had a buddy want to learn linux via Kali (while not already being a network guy). Too steep. Yes, learning by Slackware is probably best, but who has time for that?
Learning on Kali? If I remember correctly it's core functions revolves around science (forensics) and internet security but with an offensive approach. (Tails maybe?) ) It was beyond me when I first started hopping and it is beyond me now I've settled. I started out on Debian and then Mint, got frustrated fast but found Lubuntu and xbuntu on the way back to Windon't. Figured out how to dual boot and went back and forth from Zorin (which is where Windows defectors should start) to windows and I'd say 100 distros over two years. Found, really liked and ran Deepin for about a year until a new release destroyed a good thing. I liked Peppermint (alot) but could not get the display settings to run three monitors like I wanted. Got really frustrated and went back to Windows waving a white flag. Bali, Elementary, Pop, Knoppix (which i still use on a thumbdrive to fix anything that won't post and craziest community EVER...) Mate, Budgie, Ubuntu (So inflated it is now the worst distro of all time). Alpine, Slax. Slackware, Gentoo (too complicated) and of course all the Puppy Linux distros (could never get the internet to cooperate with me on any Puppy distro) all pretty much sucked ass. I settled on 4 distros finally after about a year of hopping.
Mx Linux - Just wasn't ready then. Three releases since and it looks to be finally where i seen it going. May try again now that w7 is at end of life
Sparky Linux - was one release away from being what I needed. Same. May try again
PC Linux or OS Linux (I forget) - would have been my full time distro but again damn bluetooth/wifi card issues with a certain driver that literally 9000 people a day had the same issue yet it still isn't fixed to this day
Linux Lite or just Lite - has been on all my other machines for over a year. Except my server. (Ubuntu's only usefulness) . The only machine still running Windows is the one I'm on now. 3 days ago my PC updated itself and displyed a warning about W7 EOL. Today I finally go completely Windows free lol.
So yeah TL; DR Windows users who are thinking of switching should try. Zorin, x or lubuntu, Puppy Linux. Linux lite and or/Sparky Linux
Distrowatch is the best resource on the web for Linux Releases
Win2k was best Windows, fight me y'all.
W7 chump
It will be a little different because from Unix, like Mac did, unlike windows. The most noticeable first difference is the lack of a C drive. The entire file-structure is different which could make you feel a little off balance at first. So long as you don't run everything as root and delete things without research first you're pretty safe.
This was the biggest hurdle for me. Windows had taught me literally nothing and when I tried to switch it showed.
