Sony/Zeiss 16-35 or Zeiss Batis 25?

All;

So, I'm pretty new to Sony. I just picked up a Sony A7II, Sony/Zeiss FE 35mm F/2.8, FE 50mm F/1.8 and an FE 70-200 F4 Sony lens.

I would like something wider than the 35, but I'm not sure that I'll ever need anything as wide as the 16 in the 16-35 zoom. Now, Zeiss has introduced the 25mm Batis prime.

I'm wondering if the 25 on its own is too similar to the 35, or quite a bit wider? The Batis is smaller than the FE 16-35, but it's not a small lens - it's actually almost the same size as the Batis 85mm. What are your thoughts regarding the 16-35? Will it be a more versatile choice than the 25mm prime? Do you guys ever use 16mm as a focal length?

Thoughts? Comments?

Thanks

Brad
