I am a litle confused about what are these two models are prezent. What are the benefits of VPM and what are the benefits of BUHLMAN.
Sorry for my English.

Depends on the dive, and how you tweak the algorithm...Wich of those two (VPM, BUHLMAN) is more conservative?
Remember, because of the widely differing variables from person to person and from day to day, all decompression algorithms are akin to measuring with a micrometer, marking with chalk and cutting with an ax.

VPM is programmed into V-Planner software.
Buhlman is programmed into NitekHE dive computers.
I have not noticed much difference between them, within the ranges of 10 meters to 75 meters. I have not tested either of them deeper than 75 meters yet.
I normally use the VPM (V-Planner set at +3) for planning dives and gas volumes, and as laminated backup print-outs to attach to my O2 bottle. And then I dive with the Nitek HE computer (which uses Buhlman) and check it against the VPM print-out during the deco phases (after all the short deep stops).
The minor variations between these two programs is academic. There really is no perfect model. Even GUE's "deco on the fly" if you want to go through the mental hassle of keeping track of it, is adequate, and compares very similarly to either of the others.
