S905 vs S905x performance is VERY different. My S905 T95M is SOOO much faster than my S905X based A95X. Just to make sure that I was not taking something into account, I updated both boxes to the most recent ROM 8.1.6, then I backup up my A95X and restored it onto my T95M and just began to do basic stuff like clean libraries, drill down through menus, run TRAKT sync, etc. and in every instance my T95M just blows the a95x away.
I looked at the specs of the droid-O2 and tried to match the specs with TV box, and I think I found my perfect unit. The droid-o2 was very expensive and it came with no case or remote. So matching the specs with the droid-02, I think I have done much better than I had anticipated.
