I say this with the intention of providing context, not to say the way you do things is bad. It's all user preference in the end and there is no wrong way.
Lots of folks consider your "fast" example with a mouse as their "slow" example that forced them into learning more advanced features of their editor. For example. Most Vim users can get to any character or partial string, or parameter, or line, or paragraph, or function start or what you have within three quick keys on their home row. They do this quickly, and can immediately start doing other things right after because their hands never moved.
The mouse is fast because people don't need to memorize things. The keyboard is fast because the keyboard is fast.
It's like the old joke from the movie Heist. "What do you mean you don't like money? That's why they call it money".
