TL;DR Summary
Time to the collapse macroscopic object depends on its mass/momentum or complexity?
Does the time to the collapse of a particle system depend mainly on its mass/momentum, or complexity? For example macroscopic object.
If system is quite isolated, is no spontaneous collapse even massive or complex systems?

time to the collapse
There is no such thing in standard QM. What model or interpretation are you asking about?

For example in Wojciech Zurek theory - decoherence time (although decoherence not means collaps)

Which is not the same thing as "time to collapse", as you note. What do you want to ask about?
 
Perhaps the OP means to ask if the "time for the Shoedinger wave function to collapse" is affected by the "mass/momentum" of a macroscopic object or by its "complexity". @AndrzejB: is this summary appropriate?

(Quote marks because I suspect some of the assumptions made)
 
@DStahl all you have done is repeat the OP question, which has the issues I have already pointed out. We don't need anyone else repeating the OP's question. We need the OP to clarify what they want to ask about.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
