Descriptive notation sounds better but algebraic form is neater and more precise, eg How would you say which of two possible pawns KB4 & Q4 would take a pawn on K5? D4xE5 is easier than PQ4xK5.It's a reasonable rule of thumb for a novice as F2 is one of the weakest squares on the board - but like any rule you need to know when to break it.
Also, call me a old git but I prefer the descriptive notation to the algebraic form. I know the algebraic (E4) has been the official standards since the 90s, is easier for beginners and is always unambiguous but the descriptive style (PKB4) gives more information.
The fact that numbering is different from the white and the black end really used to cause me headaches if I wanted to compare my game record against that of my opponent!
On top of that, if you are really screwed if your opponent is foreign and uses different terms from you, say they are Spanish and use R (rey) for king, D (dama) for queen, C (caballo) for knight or T (torre) for rook (they literally call it a tower).
