Blender has inverted left and right mouse buttons by default which I think isn't like vim but just a very bad UX decision that's not being changed now since the old user base probably adapted.
Some bad UX decisions get baked in and you have to live with them, though the nice thing is Blender can be switched to operate in completely different flavors. There's one that matches what Maya does quite closely for those who prefer that.
Check your User Preferences options. It's extremely configurable.
Blender's UI isn't intuitive, but it is fast and quite efficient.
