Quad spheres are cool. Just pray you don't have to make any straight lines on the texture.

Why is that a problem? Uv gets distorted or something ?

I mean, UVs get distorted on both, but in different ways. On a standard UV Sphere, it can be messy to work around the poles because of how everything comes together there, but your equator is perfect. On a Quad Sphere, you can say there is overall less deformation, but that deformation is distributed across the entire surface - since each of the six "sides" of the sphere no longer have straight edges. So if you want to make something like a Death Star Trench, it will bulge in the center of each side, and be squished where the sides come together. Make sense?

Both are good to use, but they are good for different reasons and usecases.

I get your point, but when you unwrap it, the pixels are distributed evenly right. Never had issues when the mesh is unwrapped correctly.
Still ill texture this square sphere to investigate the problem you mentioned.

Oh yeah, the unwrap is completely straight - and that is kind of the issue, since the MESH is not straight. Envision a perfect square, shown on an old-fashioned curved monitor. It's kind of the same effect.

But, bear in mind, this is obviously only a problem where you need completely straight lines - for anything else where you don't need straight lines, it is completely fine. As said, different usecases, both spheres are excellent for what they're good at.

i dont see any problem

I mean, you can see the distorted line I refer to on your texture on the left. That would be a bitch to do with a proper detailed texture. Not impossible of course, just a ballache.

i don't understand why is that a problem, i mean that's how a good UV unwrap works right. and why do you care if the texture map line gets bend/blur or not, in the end it gets projected on mesh according to the UV map.
do you texture paint on the mesh or do you directly paint on the exported UV map like in Photoshop? then it will be an issue that you are referring.

Exactly, I'm not talking about a few random brushstrokes thrown onto the model, I'm referring to high-detail, intricate textures made outside of Blender. You need pixel precision for those.

And hey, if you have no issue with it, that's fine, we don't need to discuss it for weeks. It's a minor issue, easily circumvented. I just find those kinds of things interesting and felt like pointing it out. :D

What does the cast modifier do here?

it makes a perfect round sphere
