I have tried numerous different tyres on my Imprezas over ther past 13 years.
The best for warm dry roads have been the Bridgestone RE-070s, but these are a complete nightmare on snow or cold/wet or frosty conditions, esepcially on uneven raod surfaces.
Goodyear F1s are great in the wet, but their softer sidewalls don't give the same level of confidence when psuhing on in the dry - they have a tendency to feel a bit spongy though you do start to get used to them after a few hundred miles.
I've had a couple of sets of Toyos, and found them to be great in the wet when new, but not nearly so good as others (F1, Bridgestone S-02) when part worn. I also had one set of 4, two of which had very soft sidewalls which were replaced free of charge.
Overall, the best compromise tyre I've had so far has been the Michelin Pilot Sport PS2. Probably 90-95% as good as the RE-070s in the dry, 95% as good as the F1s in the wet, good ride quality and relatively low levels tyre noise compared to the others. Reasonable levels of wear (I've done about 14k on my current set swapped every 6 months front to rear), and will probably get another few K out of them once I swap them back on in place of my winter tyres. The only downside is that they are more expensive than some of the others, but they are a great overall tyre.
