Does anyone have any positive changes since being on Levothyroxine?

Most of the people here talk about their side effects when starting the hormone therapy. Now I wanna ask what are the positives of being on levo except the blood test that comes normal (which doesn't really means anything if you still feel like sh*t). These question is specifically for those who have developed hypothyroidism due to their Hashimoto's because if you didn't have hypothyroidism on the first place then the hormone doesn't change anything for you (it actually can make things worse)
