頑張る　and　最善を尽くす differences
頑張る does not have the meaning of "my best". ALC gives [20 possible
translations of
頑張る](https://eow.alc.co.jp/search?q=%E9%A0%91%E5%BC%B5%E3%82%8B), which do not
include "do my best". It is just "to work hard".

頑張る is fairly common, and 最善を尽くす is a big and serious set phrase you should
use sparingly.

answer
頑張る sounds more "making strenuous effort" which can be positive or negative.
It can imply you are giving it your best shot or you are just wasting
energy/trifling in a different context.

However, 最善を尽くす sounds one is trying to find the best scenario as much as
possible. It does not sound like "brute-force".

Probably, in a medical situation, saying 頑張る : "do one's best" does not take
patients to be comfortable to receive the service by doctors. I think 最善を尽くす :
"using the best solutions as much as they can" relieving patients more.
