Dave Smith Instruments SYNTHESIZERS

Hi,

Evolver is great as synth but does anyone use it as filterbank?
I'm planning on buying a Sherman 2 and I own an Evolver.
Just to be sure I'm not buying something I already have I would like 
to know how close an Evolver can come to a Sherman 2.
My guess is they are totally different and the Sherman is much better 
as filterbank.(and sound better)
Ronald.

PS. This may sound a stupid question - I know - why would one use 
such a great synth for something else?
