Stuff like typing "10j" made sense when text editing was high latency. Nowadays you can just hold j and stop precisely where you wanted to, even if you're ssh'ing into a server on the other side of the country. There's nothing wrong with it (and in fact I prefer it because of the 0 finger movement required).
The only times I use "precise" movement commands like that is when I'm in the odd situation of having to ssh into something from my phone.
