Is this a trick question, or an attemp at humor?! The Atma-sphere MA MK II.2 (now upgraded to the MK II.3) and the VTL-750 are in two different leagues!!! Comparing the Atma-sphere to the VTL is like comparing a Porsche to a Yugo! If you check out the specs, design phylosophy and circuit layout, and company histories and REPUTATION, it's a "no brainer". Go with the Atma-sphere. You've been forewarned.
