I have Saphir and Loake cream polishes, and mostly use the Loake.
The Saphir cream seems to be absorbed more quickly into the leather, but the Loake gives a better shine - not as glossy as a wax polish, but really not bad at all.
I'll use wax polish a bit more during the winter for a bit of extra protection against the weather, but I'm still on Kiwi and Cherry Blossom for that.
As others have said, Saphir is a solid choice for all their offered products.
Generally goes: Kiwi->Lincoln/Melatnonin->Saphir for what's available in the US. The UK has another brand or two that look good but I'm a yankee so who knows.
