It is big debate between crypto earners.

Electrum enables you to do cold custody at almost zero cost and free of third party HW gadgets. https://electrum.readthedocs.io/en/latest/coldstorage.html

Electrum is good for hot and cold L1 wallets. For LN Coinos is my favourite as it is very easy to use and operates on any browser on any OS and the fees are the lowest I know of. Because it is not self custodial do not leave large numbers of sats on Coinos but it is useful as a LN wallet for spending sats. The fees charged on some other LN wallets are bordering usurious.

Do all your serious L1 Bitcoin computing on Linux, if at all possible. Most other operating systems are fundamentally compromised.
