Does anyone have the exact numbers of how much protection you get using a 24 word seed vs using the conventional default standard that shows up automatically when you create a wallet in Electrum?

It's still not clear to me that you can trust this type of wallet, that could be bruteforced and then all of your keys are compromised forever as long as you keep creating them on that wallet. It still seems safer to use a wallet.dat file. I want to see the math.

From what I know, they are safe enough against brute force, some numbers should be on reddit. They say that for 12-word Electrum seed it would be needed about 10¹² years.
And from this point I think that 24 words is just extra hassle. Maybe it would even help more to add your favorite word as custom word, but I am no specialist.

What about key derivation. What are the chances that one could derive a seed by taking control of a public master key and something else? I've heard some concerns along the lines about key derivation which is why I just would avoid seed-based wallets altogether and would focus on the classic wallet.dat format but I haven't studied the details, I have just heard conflicting opinions.

As far as 24 being too much of a hassle.. well I doubt you can trust your memory to memorize 12 words for the long term, so would need to type the seed somewhere, so if you are going to type 12 words you might as well type 24.
