If only owning 1 L lens, which one: 35mm 1.4 ii, 24-70 2.8 ii, or 50mm 1.2?

I re-entered FF DSLR world with 6D2 and 24-105 STM and 50mm 1.8 STM. I wanted to keep my initial lens investment small, and with those 2 lenses I can actually shoot anything I want/need. I'm a hobbyist and primarily shoot people.

I've always wanted to add 1 high quality L lens to the lineup, and just one, due to cost and wanting to avoid GAS. So the 3 I am choosing from is the 35mm, 24-70 f/2.8, or 50mm. I have used the 24-70 before so aware of it's quality, have not used the other 2 before.

IF I was only limited to carrying 1 lens, then the 35mm focal length is the one I prefer and most versatile. But if I have any kind of zoom available, I prefer a 50mm. So it's a tough choice, I could see any 1 of these 3 getting a lot of use from me.

So, if I could only have 1 of the 3, which would be the best choice?

So tough to say because they are all different.   If you get one of the primes, will you keep the 24-105 stm?

The 35mm f1.4L II seems to be an absolute stunner in performance.   In sheer image quality, it's the best of the three.

If you want a really good all-in-one lens, then the 24-70 f2.8L ii is the way I would go.

If you like primes and like the 35mm focal length (I personally do and I think it's the easiest focal length to just put on your camera as a prime and keep it on for awhile), then the 35 is amazing.

Between these three, the 50mm has the worst IQ and I personally wouldn't choose it, but some like it.
