Personally I've found my success rate with WINE to be more around 80 to 90%. In fact in the last year I've only needed to use it for for 3 different tools, all of which worked flawlessly (in fact it later turned out that one of those tools officially supports WINE for their Linux support).

My convoluted point is that it really depends on what you throw at it. Anecdotally I've found stuff that ties into DirectX to be the most awkward and since you've mentioned 3D packages I'm not at all surprised you have had less success with WINE than I.
