Powershell (and cygwin as well IIRC) still have lousy terminal emulators. The issue isn't the lack of good programs nor the shell, it's the Windows GUI "wrapper" around the CLI shell. In Windows neither cmd.exe nor Powershell allow you to alter the width of the terminal in real time. Nor have sane copy/paste options, region highlighting and so on. There's no tabbed grouping, clickable URLs, etc. Sure, some of the aforementioned can be tweaking in the preferences. But on the whole, the Windows terminal emulators are pretty poor when compared to (for example) Konsole.

Cygwin is pretty awful as well. I hear a lot of people suggest it but I really couldn't get on with Cygwin. I found MinGW to be a much better solution (which also ships some pretty cool terminal emulators as well)
