verb+べき expression

[nonezumi]

Hello,

If possible, please, kindly help me with a difference in the following sentences:

もっと にほんごを べんきょうする ほうが いい。
もっと にほんごを べんきょうするべき です。

Maybe, both sentences means You should study Japanese more. But unfortunately, I am little bit unclear, if there are any subtle differences.

Another difficulty is with negative expressions. Would it be correct to say You should not call him using ～ほうが いい and ～べき as follows:

かれに でんわしない ほうが いい。
かれに でんわしないべき です。

Thank you very much!

ほうがいい : would better ～
べき : should

ほうがいい is merely a suggestion/opinion while べき is much stronger.

かれに でんわしないべき です。

かれにでんわするべきではありません is correct. You can also use でんわしてはいけません for "shouldn't".
