Makes sense. Perhaps he'd only just created it around the time of the Buu saga, and was only just learning it's limits at that time.
Re-call the original Super-Saiyan form was pretty stressful even when Goku had already mastered transforming in and out of it. He had to learn to hold the form indefinitely before he fully perfected it.
One Strip! One Strip!The thing about SSJ3 is that it's a lot like Freeza at 100% power or in Golden form: It's stupid powerful (in this case, being a 400x power boost) but it drains energy like mad meaning that Goku can only hold it for five-to-ten minutes.
Let the joy of love give you an answer! Check out my book!The SSJ 3 form carries a gigantic boost in power. If you transform and you can't immediately kill what you transformed to kill, you're beyond boned anyway.
Well, until the God forms came around.

It would make all those scenes of them eating until they are stuffed a lot less humorous for one.
One Strip! One Strip!.......
And suddenly I realize just what kind of people I've been hanging out with.
......At least we're discussing something beside Power Level bullshit.

That's exactly what he means, the Super Saiyan has never had a set power level. Its not something that you can train to get stronger, just something that buffs your power level.
And yes, I would assume the current forms Goku & Vegeta use are stronger than the standard god form.
