It depends on your telescope needs. While the design may be 30 years old it is sometimes still the best option, it depends on the individuals needs.
If weight and transportability are important considerations then the newer lightweight compact designs are clearly the best choice. If however, weight and transportability are less important than stability and the ability to fit a drive system, then the Obsession design is still better than most IMO. I have used a few different compact scopes and while they are much more portable / transportable than the Obsession / SDM design, they fall short in some other areas for mine, most notably in stability at the top end.
