Yeshivitis

 Chassidim are affected by neo-Litvishism. Witness Rabbi E. Biderman:

It states (Mishlei 8:11), כי טובה חכמה מפנינים וכל For wisdom is better than" ,חפצים לא ישוו ב ה pearls; all desirable things cannot compare to it." The Gemara (Moed Katan 8:) adds, אפילו חפצי Even mitzvos don't compare" ,שמים לא ישוו ב ה to Torah." Because the greatest mitzvah a person can perform is to study Torah.

What does the Gemara (page 9 by the way, not 8) actually say:

The two scholars, Rabbi Yonatan ben Asmai and Rabbi Yehuda, son of converts, once again sat and raised the following dilemma: In one place it is written in praise of the Torah: “She is more precious than rubies; and all of your desires are not to be compared to her” (Proverbs 3:15). One can infer from here that all human desires cannot be compared to the Torah, but the desires of Heaven, i.e., mitzvot, can indeed be compared to her. And elsewhere it is written: “For wisdom is better than rubies; and all the things that may be desired are not to be compared to it” (Proverbs 8:11), which indicates that even mitzvot cannot be compared to the Torah.

כָּאן בְּמִצְוָה שֶׁאֶפְשָׁר לַעֲשׂוֹתָהּ עַל יְדֵי אֲחֵרִים, כָּאן בְּמִצְוָה שֶׁאִי אֶפְשָׁר לַעֲשׂוֹתָהּ עַל יְדֵי אֲחֵרִים.

They resolved this contradiction by stating that here, in the second verse, it is discussing a mitzva that can be done by others. In that case, even mitzvot cannot be compared to the Torah, and accordingly, one who is engaged in Torah study should not interrupt his studies in order to perform another mitzva. However, there, in the first verse, it is discussing a mitzva that cannot be done by others. In that case Torah study is not more important than the mitzva, and one should interrupt his studies in order to perform the mitzva.

This is similar to the debate in Kiddushin on Torah vs mitzvos where Torah is deemed to take precedence because it leads to doing. 

Moed Katan can be read to say study before doing mitzvos others can do because it leads to more mitzvos which is God's desire. He only shows you the second verse not the first which presents a contradiction.
