Arperture size is the key here. Both scopes are of the same type of design. The larger the mirror the better you will see other deepsky objects. Example: A 8" mirror will have about 177% more light gathering than a 6" mirror. Sky conditions bad or good affect all telescopes regardless of what kind it is. If I were in your shoes and I had a choice of between a 5" and a 8", I would opt for the 8". As for stability, the better the quality the better the stability. In most cases anyway. Electric focusers are nice, but I wouldn't need one unless I was operating remotely or using a CCD camera with a flip mirror or whatever. Anyway good luck in your decision and Clear Skies!!
