As someone who's pretty familiar with both bash and PowerShell, I don't consider either of them better or worse than the other, just different. I think of PowerShell as something in between a traditional command-line shell like bash and a scripting language like python, with a mix of the strengths and weaknesses of both. It's not the best of both worlds, nor the worst of both worlds (each of which I've seen comments online arguing), it's just "some of the good and bad of both worlds."
