Talmud Torah or Chesed more important?

I've been to a lot of Chabad shiurim and have been getting this message that Chesed is the most important thing to do. We are here to do chesed to one another..

but in the morning prayers i feel we say its talmud torah that is most important we say; that in this world we eat the fruits of study of torah, and in the next world, we benefit from performing deeds of kindness, (...) and the study of Torah is keneged culam.

Is it even possible to study Torah and to not have one's heart open more and more?

So hypothetically, if say I had only one hour a week of free time, should I study Torah or go do some charity work (or other forms of chesed)?
