Is inbound marketing better than traditional marketing for B2B?

Each way has different way to achieve 

both inbound and traditional marketing have their own advantages, traditional marketing will always score in the long run.

inbound marketing will need a long drawn process laid out thru detailed online campaigns based on various attributes of your product/service, the same will have to be targeted to a extremely large audience with most of them not being part of your TG.

B2B marketing will always be based on a detailed analysis of your own product/service and matching the same with the TG. One successful closure will lead to building use-cases, references and highly positive word being spread out. The only hiccup will be, the traditional approach is a time consuming activity and one will have to walk one step at a time.

A successful traditional campaign can lead to a highly productive in-bound campaign.
