I personally have no desire to use it outside of Windows, but Powershell fixes all there things if you're so inclined:

> flags are inconsistent

At least among the core command set, there is a set of "core flags" like -ErrorAction or -Verbose that are consistent. Though I don't know how often you'll find them in third-party commands.

> case sensitive

There's a preferred case that you'll get if you tab complete, but -Verbose is -VERBOSE is -VERBOSE.

> not good discoverable

Tab completion works for flags everywhere and each of them should be included in Get-Help regardless of if the author documents them.
