They show similar +information and are all open source under the MIT license. I tested each one +on: Arch Linux, FreeBSD 12.1, macOS Mojave, and Windows 10. At the time of +testing, all three failed to build on FreeBSD and Windows. Figures below are +from the Arch Linux system, which is a [12 core AMD Ryzen desktop PC][ryzen-pc]. + +`ytop` and `bottom` use a layout that appears to be inspired by [gotop]. In +fact, `ytop` is written by the same person as `gotop`. `zenith` uses a layout +that's a bit more like traditional `top` with and histograms above the process +list. + +I typically use `top` to: + +* Check on overall system load and free memory. +* Find specific processes that are using a lot of CPU or memory. +* Observe CPU and memory use over time. +* Occasionally kill processes. + +I find the `zenith` layout more information dense, with less space taken up +with graphs. I also like the header row with info and help. The main feature +that it is missing compared to the others is temperatures — but that's in the +list of planned features. There is one issue with `zenith`: it doesn't show my +ZFS pool. My system has an NVMe system disk and a ZFS pool of 3 SSDs that is +mounted as `/home`, which is absent in the disk summary. I've raised [an issue +on GitHub][zenith-zfs]. + +The individual lines for each CPU in `bottom` makes the display quite noisy. I +prefer the aggregated line that `ytop` shows. `ytop` has a handy `-m` option +to only show CPU, memory, and process list. + +So, after reviewing them all I'm going to start using `zenith`.
