Welcome to Autopia!
I haven't tried the Zaino but I've used the Griot's quite a bit. It has a "leather store" smell, which isn't how my cars with leather interiors smelled orginally. It's OK but not any better functionally than Pinnacle (chich smells about the same) or other decent leather treatments. Sure not bad though.
Unless your car smelled like a leather goods shop when you got it, I wouldn't expect the Griot's to make it smell like new
There are a lot of different-smelling leather treatments out there, including Lexol, Leatherique, Zymol, that have non-leather-store smells. Hard to say which one you'd like best.
IMO the only way to find the leather treatment that works/smells/etc. the way you want it to is to try different ones. I'm using different stuff on the S8, A8, and Jag and will end up using who-knows-what on the other leather interiors (if I ever get them back from the mechanics

).
I haven't tried it yet, but I got some Leatherique to try on the good cars. No idea what it'll smell like, but it's extremely popular with people in the Jag and Rolls Royce clubs who use it on Conolly leather, which is *not* supposed to smell like a luggage store.
