Strut-tower brace noticeable diff?

I know this brace is supposed to eliminate flex, but is it a noticeable difference under hard cornering, or would I be better off going to larger anti-roll bars first?

I have a 98 GP GT.

If going to larger anti-roll bars, which is the best investment first, the front or the rear?
If going low budget, will switching to non-rubber links and bushings be a noticeable difference? or should it just be planned with a new bar?

Best low budget kit out there is the GMPP kit.

comes w/ everything 2 sway bars, 2 strut bars, 2 trailing arms

I unerstand that under normal driving conditions you would not feel the body bending. It would take really hard cornering/turning to feel the brace, bars and arms helping you out. The car OEM is pretty stable. The brace is more a body torsion reducing tool(would help a lot more on quick, sharp cornering or passing) under pretty hard driving conditions or heavy load.
The GMPP kit covers everything, body torsion and suspension support and resistance. IT is nice
