[venturaII]

Of the three you listed, I've only been on the Sumi ZIII. That said, while it was a fair enough price/performance value, it got very loud towards the end of it's life and did not wear predictably; VERY sensitive to camber. I think the Conti ExtremeContact is a better alternative for similar price, plus it's a hair lighter and it's wet performance was out of this world. I've tried autocrossing on both, and while they're not 200TW tires, they did respectably well.

As mentioned, the Firestone is just a rebranded Potenza RE003, which apparently is a decent tire but has been around for a little while now. The new Potenza S007A seems like it might be a good candidate for a hot street tire that is tolerant of infrequent autocross/track days, and the pricing looks good too. 240 TW rating suggests it's pretty sticky as well.

Real track/autox tires like A052, RE-71R, etc. would likely be slower until you put some heat into them, which is fine when tracking or dodging cones, but on the street where occasional fast bursts are relatively infrequent and tires will run colder, the others would already be closer to their optimum temp.
