At the same time we shouldn't also ignore that self-custody comes with its own challenges, I mean we heard and seen cases where people lose their wallets and their seed phrases. Buut even with those risks, one thing is still certain which is that once you give up your keys, you have given up your control. To me, that’s enough reason to say "YES to self-custody, and NO to custodial platforms."
You mentioned challenges and that is exact problem of centralized custody. Look at two things here:
Self custody: you are going to be the one to hold your coins responsible for security and proper safeguard of your seed phrase or private keys. You hardly get comprised and you don't have to worry about anything because you trust your intuitive measurement.
Non custodial: Both you and the custodial will be the one doing the security check, you will be the one to keep your email safe, a password for login and, 2FA while they keep the coin for you and they manage seed phrase. The risk here is both you and the custody can get comprised, email can be easily hack and exchange hot wallet can be hack too and that lives both of you in danger, your coins might get stolen if things go wrong with the custodial.
Instead of relying on both your security and that of the custodial, why not be the custody of yourself and sleep well at night. Safe custody remain the best.
