Comparison between htop and top
- In 'htop' you can scroll the list vertically and horizontally to see all processes and complete command lines.
- In 'top' you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident).
- 'htop' starts faster ('top' seems to collect data for a while before displaying anything).
- In 'htop' you don't need to type the process number to kill a process, in 'top' you do.
- In 'htop' you don't need to type the process number or the priority value to renice a process, in 'top' you do.
- 'htop' supports mouse operation, 'top' doesn't
- 'top' is older, hence, more used and tested.

It's the best drop-in replacement for standard top, has nice colors, tree view (highlighting the executable and threads, etc), columns are of course configurable, and the coolest features are the built-in syscall tracing and listing of open files for any process.
htop 3.0.5 shows TIME+ as user and system time by default. This can be confusing with multicore CPUs.
I have no idea how to configure elapsed time with htop 3.0.5.
Overrated. No graphs out of box. No support for GPUs out of box.
Agree, I don't know why everywhere in the internet I see that top and htop are the best. I use Linux for several years now and still not get used to this apps. I want to clear view of memory and cpu usage by each process
