Robin says that the 25/1.8 is wider than the 25/1.4, but if you notice, in most of the bokeh comparison pics the framing is actually tighter in the 25/1.8 shot, meaning that he didn't shoot from the same position and he focused closer with the Olympus lens. That can make a pretty substantial difference for background bokeh.

So you're saying any photographer with even a modicum of skill can overcome the difference?

To the same degree as a difference between f/1.4 and f/1.8 lenses in their 50 or 85 mm FF flavor could be overcome. There are scenarios where the difference can be overcome, some scenarios (like landscapes stopped down) where it is not important at all, and yet some where the difference is critical -- and for those few photographers pay x2-x3 the price for this extra 2/3-rds of a stop.

Case of point: Nikon f/1.8 (50 mm and 85 mm) lenses are minimally (if at all) optically inferior to their f/1.4 counterparts in the overlapping apertures range -- but they are 2.5-3 times cheaper.

As a matter of fact, I think these 2/3-rds of a stop are more critical in m43 world than they are in FF world. That is, the scenarios where you need extra subject isolation are far more often: with FF the DOF becomes so thin at these apertures, that you stop down just to "get both eyes in focus".

Not so with m43, where you will find yourself shooting wide open (FF equivalent of f/2.8 and f/3.6 respectively) all the time.
