Depends on what the use is....

For shooting trap...my 1957 Browning Superpossed
For Skeet....my 1934 Winchester 21
For Grouse....my new Browning in 28g
For deer...my Mossberg 500 with a rifled barrel
For Peasant...my 1969 Browning Lightening or my Remington 870 Wingmaster in 20g
For home defense....my Remington 11-87

But I also love my Browning Auto 5 and my Remington 870 Wingmaster in 12.
