Offset vs revolving credit
Offset links a savings account to your loan — the balance offsets what you're charged interest on, and stays fully liquid. Revolving credit is a large overdraft-style facility: your pay lands in it and expenses come out, so every dollar sitting there reduces interest day to day. Same saving mechanism; revolving credit rewards discipline (spend it and the benefit vanishes). Not every lender offers both, and offset facilities sometimes carry a small fee — an adviser can tell you what's available and whether it beats just fixing sharper.
