Unsolved Dildos, strapons and vibrators - Oh My!

[lololulu19]

I would like some opinions on this:
What would you, or what do you think other people would prefer?

A. To be fucked up the ass for a few minutes with a generic blue rod of silicone by a person wearing a strapon harness
or
B. To be fucked up the ass as long as you like, whenever you like with a realistic dildo that has a suction cup base to be attached to any smooth surface AND that dildo can both vibrate and thrust in and out by 1.5 inches

Obviously, the main difference is solo vs duo. Which do you think is better?

After answering that, how would you compare A and B with
C. To be fucked up the ass by a real cock. I remember one performer who absolutely refused to take any toys up his ass, and only wanted real cock.
