Another vote for Facebook. We got our best leads from this platform. Advertisement is not cheap (depends on your niche), but for us it worked just fine.
I would say LinkedIn is a good one. Bigger database too.
Facebook and Pinterest both the platforms have different sets of audience, It completely depends on what set of audience you want to target. Facebook being more vast then Pinterest I would suggest you go for Facebook advertising. All the best.
The Most Effective Lead Generation Channels:

I would prefer LinkedIn for lead generation. Facebook Ads can also help you promote your business but it helps e-commerce businesses more.
Undoubtedly Facebook is the best platform for lead generation
