Travel BC owners, why?

[MacDuyver]

Divers who have a home BC and a travel BC, what do you get out of having different BC’s?
Assuming we aren’t talking one for twins/ side mount and the other for singles.

Not sure if this counts, I’ve a small backplate, single tank adapter and the small Halcyon Eclipse wing which is specifically used for diving at a Sandals resort for blowing bubbles.

My other wings are sidemount and on a rebreather.

does Sandals have specific requirements?

Open circuit on a cattle boat.

I guess I’m a snob as I’d rather bring my own kit than dive their “standard” rental BCD, regs, mask and fins.
