Fail. You actually press the same number of keys in your keyboard in vim, unless your keyboard has an uppercase O key. On top of that, the vim combination is fugly to learn, while the other way is just logic and common sense use of a modern editor. Finally, you can create macros or templates for that in modern editors, even have them generate the enclosing brace.
As for pipes in UE, you're right, I haven't found them either. You can run commands on active files but not pipe selections. You can create shortcuts to commands and do some more stuff with Tools configuration in the Advanced menu.
