Which of this would be better in the bridge position for these genres:punk,alternative rock and hard rock?

Semour duncan SP90-2 hot soapbar or SP90-3 custom soapbar?

Either one of them would work, it just depends on what type of tone you want.

The SP90-2 has more upper-midrange detail when compared to the SP90-3.

The SP90-3 has more compressed dynamics and a sharper attack.

If you want a more punchy sound, go for the SP90-3. If you want more dynamics and boosted upper-midrange (which helps you cut through the mix) go for the SP90-2.
