Both have a huge emissions cost and are very expensive, while Germany’s economy is doing poorly. Realistically countries will not succeed in replacing fossil fuels with nuclear or renewables, let alone both. And if everyone rushes to build at the same time (as would be necessary) the price of every input will go through the roof. There are a myriad of issues with both technologies but financial and ecological costs are simple factors that can easily be analyzed for viability, and so far the numbers don’t work out for anyone.

I’m reality, the world is burning and both techs will mitigate.

I find this unlikely because currently neither acts to mitigate.

None of the renewable energy that has come online in the past few decades has reduced fossil fuel consumption. Instead, it increased our energy-available (while fossil fuel consumption also increased) and we immediately utilized that additional energy. We now use more fossil fuels than ever before despite the renewables. This is called Jevons’ Paradox - adding more lanes on a big road just causes more lanes of traffic, not more throughput. More energy in the grid means more energy is used, not that non-renewable energy will be replaced.

If there is any chance at all left, it isn’t going to come from greenwashing industries. It would come from the degrowth of those industries.
