1) BlueStar RBCT304BSS

The rest are functionally almost identlical.

It is also difficult to argue that there is significant quality differences. This is not a range or even a rangetop but a very simple drop-in cooktop.

But if you want to split hairs

2a Jenn Air
2b Dacor
2c GE Profile

Bluestar is in the JennAir Dacor price range.

But if you don't want to pay the price of the Bluestar I would get the GE Profile.

Thanks for you input!!
