I haven't had either scopes but have had a few Tak scopes and one WO.
The WO was a high end APO 90mm. It was poorly made and despite having a nice Lomo lens gave horrendous aberrations. I found out the focuser was way off centre. Poor first experience with a WO. So quality control comes into this.
Tak on the other hand have always been top notch and near or best in class.
What I have found true over the years is that extra level of quality comes at quite a bit higher price. But you don't need to sell at a loss and rebuy the better scope later. So you end up being better off getting the best scope you can afford at the time rather than a series of compromises.
Scopes have several features to consider. Some have already been mentioned.
Price is one, accuracy of optics is another, lens design and materials used (FPL53 or some other lesser grade glass?).
Focuser performance, availability of accessories that actually work (flatteners, reducers).
I would be hard pressed to believe a WO could match a TSA. Perhaps it does but I would bet it doesn't as an imaging package, as to accuracy of the lens (TSA strehl would be over .95 what is the WO?).
Quality control and lack of duds is another and a big one in our hobby.
Greg.
