Which all of them, which cron implementation is simpler and better? Do you even use cron? It’s not a joke, explanation on how to use cron takes > 8 pages. It should be in the hall of fame of the least accessible and hard to learn programs. Lennart cancer is one of the greatest things that happened to linux.
I’m not the OP, but I can explain how to use cron in like 4 sentences:
Edit cron with the command crontab -e, this opens your text editor. If you want your jobs to have environment variables, put those at the top. Put this header at the top: # m h dom mon dow command
It means minute, hour, day of month, month, day of week, command. Type in numbers for these values or a star which means all of them. Command is the command to be run.
And then with your explanation it goes: cron job doesn’t execute for reason, crontab -l lists not all jobs, someone else put cron job in whatever directory like cron.daily, you’ve added or removed empty line at the end and now nothing works, debian crond and redhat cronie ahave different quirks, etc., etc.
I’ve dealt with insane cron problems for so long that switching to timers was like *whoa i don’t need to suffer?*
Maybe I’m just lucky that I haven’t run into insane cron problems :) I’ve done both, I guess I just need to do more systemd timers and get used to it. I found it so confusing and weird to set up.

You can explain timers the same way.
And then with your explanation it goes: cron job doesn’t execute for reason,
