There is no best...
If you think you can achieve a level of professionalism by - copying what others have done, or use... your partly right..
In a wet darkroom there are dozens and dozens of papers, grades, surface textures, weight and on and on and THEN many ways to process these papers.
You also have to take in consideration the film and it's properties and how IT was exposed, and then exposed on the paper. There is also the light source of the enlarger, condenser vr diffusion, and the physical make up of the enlarger it's self. Just how DOES the light get through the negative and down on the paper...? Enlarger filters..? Hmmmmm, gelatin or dichoric glass..?
These things and a lot more make up a final print worthy of being called - pro work... If you don't understand the complete process, from picking your film to picking your paper to put that image on and then the kind of light to use in enlarging, you don't have a chance..
By going out and buying "paper" you just hit the tip of the iceberg. And... if your talking ink jets your in another world again with many variables.
A print made on one Brand X printer may not look so good on printer Brand Y printer when using the same paper. The inks are different and react differently with different papers. Yes, printers can be fine tuned in many ways to accept almost anyones paper, but some work better out of the box than others with different brands.
