well - is hard to say more than: Stability, rigidity, better precise/fine focus. you won't see any defection and both will hold the load. With stepper motors both - with ASCOM interface is a great pleasure to use. Parts are widely available and both have great customer service... I am sure that Baader was used recently on RC10 with heavy train, and with good result as well. What i want to find any problems with it? i: i would apply pressure by the eyepiece see if there is any flecture, listening to any clicks - bearings, signs of worn out paint by the tracks...how much light is going through, also, do i like the way brake is applied/catching...
I only had a problem few times where - i presume - previous owner has overloaded its bearings.. i had to replaced two- With FT they are positioned in slight different angles - careful.
