I love being able to tinker with software/hardware easily... The Arduino and FPGA's require a deeper investment, and I like how I can do everything I want in Python on a Pi, for more hobbyist projects that don't have more power/processing constraints.
It's been a fun hobby project over the past 6 years, and I also do some other things like home environment (temp, PM2.5, etc.) monitoring.
I also have a few Pi Zero W's strapped to USB batteries I use for impromptu time-lapses, using a little set of scripts here: https://github.com/geerlingguy/pi-timelapse
