What? Everyone’s opinions are biased, even your own. I’m not trying to attack you personally, but you did not investigate Blender very thoroughly.
Of course Blender has capabilities to do different modes of selection:
Shift+Translate to copy… in Blender that is simply Shift+D for duplicate.
And yes Blender has modifiers… https://www.blender.org/manual/modifiers/index.html

I can understand why is taking a more aggressive stance: some basic searching on Google would reveal all of this fairly easily.
Not to say either product is worse than the other, or that they don’t have their own quirks… and no I am not an advanced Blender user so I can’t explain everything.
Yes it can do the job. It is merely personal preference which software you use. I have no troubles personally using Blender with UE4.
