Fair enough. Every service I run depends on encrypted data, so starting the machine without decrypting isn’t worthwhile in my case. I have to decrypt to get everything back up after power loss anyway.
Main advantages I’m aware of for full disc encryption are encrypted swap and system config. Overkill for some use cases so YMMV, but wanting to point out that decrypting at boot can be done.
I have one that takes d cell batteries and works great. Have used others that barely function, though
