I very often use j & k to move up/down lines. I use h & l much less frequently, as w, e, & b are usually better for that anyway. As for hitting escape, I'm almost always in command mode anyway; I don't type and occasionally escape to command mode, but rather am in command mode and occasionally insert text.
In the time we all spend reviewing my code, we could have each fixed separate bugs in the software or completed a new feature.
Look at your last 50 or 100 bug fixes. How many of them could have been caught with a simple review? Take that data and apply it to your statement here: perhaps in the time you spend having your code reviewed, you and your coworkers will fix more bugs than you would have separately. It's just that bugs not submitted aren't as visible to anyone outside those people.
Try it. Keep some metrics on "bugs" found. You might be surprised.
