You probably know the English expression on the one hand … on the other hand. It is used in the following way for comparing two opposing opinions or facts about something (note that just one half of the phrase is often used):
On the one hand, Maria has experience, but on the other hand, she doesn’t have the precise skills that we’re looking for.
I don’t really want any more work at the moment. On the other hand, I could use the extra money.
