I can't speak for the new aluminum model line, but Litespeed titanium frames are still top notch in the industry. Jut look at the weld quality and their customer service. You cannot buy a better Ti frame than a Litespeed or Moots.
A bike shop owner is always going to promote the brands he/she carries unless he/she is professional enough to give you an unbiased opinion. At the end, money talks though, so do your research by actually talking to people who own and ride Litespeeds.
