I only flew the FGR2 / F4M, but it was no slouch. In RAFG LLAD fit (2 bags + gunpod), we made 1.6M at 36K on one high level intercept as fighter; my WSO was not a happy bunny, as it screwed his final turn keys.
At LL in the above config, she was superb, with awesome acceleration. With tanks and gunpod removed she was brutally powerful. On a windy winter's day, I recall being airborne just past the app end cable, after an 8 second ground roll; this just about matches the Tiff!
In my book she was a great fighter.
