Vim uses these commands like di" (delete everything inside “”) instead of chords (holding multiple keys down at once). Both work fine. The reason vim does this is that many regard it as more ergonomic. You don’t stretch your hand/fingers out and you can keep your fingers at homerow. You might have heard about people getting an “Emacs Pinky”. It’s basically down to preference. I don’t use emacs but I know people use vim bindings in emacs (emacs is very scriptable after all). That way you can try or integrate vim like bindings without leaving your comfy emacs.
The biggest difference will be between binary packages and packages that compile from source. Yes, big binary packages like browsers take longer but it really doesn’t take that long. You should be able to quit the compilation without problems. Only after the compilation is done will the package manager be invoked to install the resulting binary.
