Homebrew is recapitulating all of the work that previous package managers have done, while making choices like analytics and stomping on /usr/local by default that others wouldn't consider. I think there's still a place for MacPorts.
I honestly really like how HomeBrew doesn't require "sudo" for anything. Random stuff I download from internet should not require system permissions to do anything they want. That part of HB design is what sells it for me.
Things you install system-wide in a folder designated as such should not really be done so by a package manager that makes insecure choices on how it installs software and maintains permissions on that directory.
