Intuative for new users is often less efficient for experienced users so for many complex professional tools that will be a core part of the users' work it probably makes sense to go for the less intuative but more efficient tool and provide training.
Note the "core part" though. Even professional tools that many people have to use occasionally (say tools to book professional travel) should be intuative because someone who uses it once or twice a year will forget complex things. But it's probably OK for a CAD program used by engineers as a main part of their job to have a steep learning curve.
