I used PS3, GYF1D5 and RE003 now.
While it is said that PS3 has better wet traction versus RE003 AND GYF1D5, that doesn't mean the RE003 is bad. What it means that if you go through a standing water - not exactly a deep puddle, but a damp patch, the RE003 will be slightly uncomposed. Aquaplane performance, PS3 is tops.
Dry tracking, that's where RE003 shines. It feels sharper on inputs, versus the PS3. I'm not sure why, but RE003 seems to give me more confidence. I've never broke traction with any of the 3 tires even powering out of the corner @ full boost, FWD.
Wet cornering, I've never really pushed it that far, cause I drive on the streets, don't be an idiot. But I have no issues with the RE003.
As for stiffer sidewall.. I'm pretty happy with the NVH of the RE003. If anything, PS3 does not wear gracefully. As it wears down, it does get noisier.
Out of the 3, I am happy to use RE003 because its the cheapest. And the performance is great. If the price difference between RE003 and PS3 is small, I'd put them on my father/mother/brother/imaginary girlfriend's car. But for myself, I'd still go with the RE003 if its cheaper. If the price is the same, I'd go for the PS3 for the slight benefit in the wet.
GYF1D5.. Dry doesn't feel so sharp, wavers a bit, wet is ok, not too bad. I'd say for Dry its slightly behind RE003, wet is the same if not better. PS3 is definitely better than both in the wet, dry its better than the GYF1D5, RE003 is better in the dry.
