I've been trying to wrap my head around Nikon's menu banks vs. the U1/2 system I'm used to (as I debate this, or a Z8).
Doesn't the U1/2/3 system negate the need for recall settings, as everything is stored in the custom mode? Unless you need more than 3 I guess?
No, the current implementation of Modes doesn't save several (5-7) settings, drive (timer,) and picture control being the most important to me. Drive is saved on the DX bodies. You also can't just change the mode of a U1/U2/U3. You have to reconfigure your PASM settings save it, and put your PSAM settings back; yes they work like another mode. Changing this on the left locking dial is finicky.
Recall Settings lets you instantly switch between two settings or sets of settings, but there is only one on the Z8/Z9. (Hudson Henry is critical of modes/banks too.)
Banks remember your last settings, you give up one, and restore to it. There are also two sets of them, extended banks, and they can't be tied to each other.
In either cases, I'd like to set global/static settings I don't change and hide them. Rather than create a "mymenu" selection which I don't care for navigating.
Sony has 3 in camera and 4 on the card modes, but there is a LONG annoying preview delay switching between them. If you format your card you lose 4.
I haven't used a Canon in a while, but they have an instant eye tracking that can be enabled from ANY mode, three physical ways to change frequent settings. Their buttons are too small for me and tricky with gloves.
NOTE: None of this was a problem with pro Nikon DSLR's because you could change everything with physical switches and (for me years of) muscle memory. Even when I tried the D780 after going ML, it was like going home.
(Joking).
