Thank you all, learned somehting in the process. I'm trying to summarize and conclude: The term "pre-image" refers to the original input data that undergoes hashing to generate a fixed-size output, known as a hash. Essentially, a pre-image is the initial value fed into a hash function, while the hash denotes the output generated by the function.
In comparison, P2PWKH (predominantly used in single-sig) is generally perceived as more secure than P2WSH (predominantly used in multi-sig) due to its simplified script, hashed public key, reduced script complexity, enhanced script verification, and increased resistance to replay attacks. Nonetheless, each script possesses distinct advantages and limitations, and selecting between them is just a matter of one's particular use case and requirements.

Would splitting coins into multiple single-sig wallets may be more secure than having all on one multi-sig? For example splitting my coins into 10 single-sig wallets vs all in one multi-sig?

Yes, you that was the essence of my question. Can you please explain this last part more in detail? I dind't quite understand the exception. Thank you!

Thank for chiming in! Yes, I'm new,  it may have been answered. I'll do another search. I am talking more specifically about the answer to the questions that: Would the attack have to generate/guess 2 keys instead of one, and moreover those exact 2 keys. Does it work in this way and would a 2of2 it help?

Hi folks, this is a very specific questions about multi-sig (2of2) vs single-sig.  I believe this was already asked, but not answered. Let’s imagine a future scenario where randomly generating a single-sig wallet is much easier and faster than today, or that there’s a yet unknown/undicovered bug that makes it explaoitable and in a matter of a few years or a decade, one could stumble upon single-sig wallets with ease.
I would like to understand if having a 2of2 would mitigate this, simply by the fact that one would not only have to generate/guess 2 keys instead of one, but those exact 2 keys. My quetions is specifically if in such an event, having a multi-sig could prevent coin acess unless the atacker can find those exact two keys. AFAIK, it’s not like multi-sig is a one biger key, it’s in fact 2 independent keys one would need to find, those exact two. Is this the case?
