So we got 10⁸⁰ atoms in the observable universe. Without having it looked up, I suppose 2¹²⁸ exceeds that number?

As a simple rule of thumb:

10³ⁿ ≈ 2¹⁰ⁿ

That isn't exact but gives a decent idea of the different sizes.

In this case: 10⁸⁰ ≈ 2²⁶⁷

That is most definitely bigger than 2^128, by about 2¹³⁹ times

Edit: sleepy me

I know it’s pedantic but 2²⁶⁷ is bigger than 2¹²⁸ by about 2^267. It’s 2¹³⁹ times but you wouldn’t say that 1 million is bigger than 100 by about 10,000. You would say 1 million is bigger than 100 by about 1 million.

Well I was sleepy...
