Which Saxophone has more pitch range ? Alto Sax , B sax, Tenor Sax, Baritone Sax ,Soprano Sax,?

All the saxophones should have the same pitch range. All the keys are arranged nearly exactly alike and there should be much of a difference. Maybe some of the lower saxophones have an extra key to go a pitch or two lower than with the normal key configuration, but other than that, they should all have the same range.
