Version control system? Git (most popular)
Linux Distro? Ubuntu (most popular)
CPU? AMD (perceived second best)
Rideshare? Lyft (perceived second best)
DAW? FL Studio (perceived second best)
This system has generally worked out well for me. Note that the popular choice is just to get me started because it usually has the best troubleshooting/community resources, years later when I'm more experienced sometimes I'll switch to something less popular (for example I no longer use Ubuntu in favor of openSUSE Tumbleweed).
