I'm thinking to buy manual juicer. I considering two options: plastic auger one or thick aluminium press.

Personally I prefer a wooden reamer.
My preference is based on durability and ease of general long term maintenance. Also because it just kinda looks cool.
From a standpoint of maintenance and long-term durability I would suggest the metallic press will be the better of the choices you provided. I am basing this on metal vs. plastic and the fact that the press has fewer mechanical parts (fewer parts means fewer breaking points).
The top auger will likely be more efficient at extracting juice. I am basing this on the fact that the torque involved should produce more mechanical force (unless very poorly designed, which may be the case based on the comment regarding product reviews).
