Airbus for some reason, due to the wing design are certified to fly approaches down to 1.2Vs. That said with GSmini operating the AoA could be quite low (high HW comp). Actually depends on flap design. A321 has a different flap design to the A320 and as such flies the approach at a lower nose attitude than the A320 and A319. However, the A321 strikes it's tail at a lower att too.
B737 is generally more nose up than A320 and B777. However I think this is non manufacturer specific, more to do with basic handling and required margins.
