Hi, about battery, well you kinda gave the answer yourself. Some will say it's great, others will say it's terrible. As we all use our phones differently, with different apps, different settings applied etc, nobody's battery usage will be the same. OxygenOS 12 has been released yes, but it's a bit complicated at the moment. Thankfully another user was so kind to create a thread with a full summary of the state of the OxygenOS 12 rollout so far

If you should switch is also hard to say... If you like the s21 ultra and Samsung's software, i see no reason to change. It's still on hell of a phone, even with the Exynos chip.
Don't know of you're aware or not but there will be some changes in OP's software, because of the merge with Oppo's ColorOS codebase, as well with the OxygenOS 12 update, I'll link those threads to check out if you want

But ultimately the decision is yours alone to make i'm afraid.
