Engine Rigger is fine, in my opinion. It's not meant to be used on every ship, just like most other briefings. Engine Rigger is the go-to briefing when you need to be able to "sprint"; that is, move really fast for short durations.
I personally found that it answered extremely well on my emergency evac light tac (substantially increasing the distance I could cover during cloak), and it can be useful on ramcans and corvettes in the right situations. A few of my friends like it especially on their medium tac cruisers, as it can help them run from a dangerous situation that much faster.
