I have the Gitzo gt3542xls and have being using gitzo tripods. LS-324CL is my first leofoto and here is my review/thoughts on how they compare.
Pros (LS-324CL): 1. Gets a few inches taller than the xls. 2. feels lighter and 3. The most important advantage for me is the compact apex compare the series 3 systematic gitzo, as I am planning to use it as my travel landscape tripod. Gitzo at its price point offers better build quality & stability. Cons (LS-324CL): Mounting plate should have been flat without ridges & rubberized (in my opinion, this would make solid contact with base of attached head). I think leofotos are very affordable option and still find plenty of use for precise work.
