At first, I did a clean install too. It was much better but still too much in my opinion. Now I flashed the stable ROM and not only is my battery life way better but also the whole system feels much more responsive and the phone stays cooler most of the time. And on stable I let Google restore my Backup again with no issues. I'm happy for now because the differences in features between weekly and stable are not this big.
What SOT and Runtime do you get with the stable version?
