Is there some documentation comparing these two for using with Fluent? May somebody has an experience with both? What would you suggest?

Gambit is more comprehensive in the overall meshing since you can do edge, face, vol mesh etc. You can get different vol mesh as well (map, cooper, tgrid). As far as I understand, TGrid needs to have a surface mesh to begin generating a vol mesh. But if you have complicated geom and want to generate vol mesh, TGrid is a wonderful tool with many features to fix cells etc. So yeah, the bottom line is it depends on what you want to use it for and what resources you have. If you don't have a tool to generate surface grid, I guess having TGrid isn't much use.

Hi. Can you find some example where gambit fails or does a poor job, but tgrid does not. Using gambit is more or less like using cad in building geometry. Is tgrid different? It has a possibility to built a geom and a mesh as well?

Pavs is right. Tgrid is good for volume meshing of high quality surface meshes. However it has no geometry core it can only handle and import meshes. Geometry core of FLUENT package is included in Gambit.

Tgrid is useful for generating boundary layer over 3D geometries.
