Keep or Sell? Tech 21 Sansamp GT2

A long, long time ago in a galaxy far, far away a small rebel pedal company in New York created an all analogue amp and cab simulator. Years later, the dark side rose up in the form of digital modeling to challenge analogue technology. The question is, should we look to the past for our ampless guitar gigs, ie the Tech 21 Sansamp GT2 or trust the digital modeling path?
