There are a lot of different types of chastity folk — sissies who want their clits nullified, slaves who are doing it for their dommes, submissives who love totally losing control of their penises, etc., etc. For me, it is mostly about taking a break from masturbating and focusing on other types of sensation. During multi-week lockups, I use an open metal cage (MM JB, BAWR and now a ChastityGo titanium) and do my daily cleaning with a hand brush in the shower, but I find that both comfort and hygiene is better if I pull out every few days and wash the peno-scrotal angle (the underside where the scrotum meets the base of the penis. Do others do that? I am never tempted to masturbate when I do that but some of the younger guys may have a harder (pun intended) time with that. I’d think that would be especially helpful for those in closed tubes.
