Hi Christian,
that kind of problem (not properly aligned in Imola) is usually Wishgranters speciality to help with. I wonder why he hasn’t posted anything since a couple of days. That’s not like him at all - maybe he’s just taking a break for once… 
Yes, there seem to be specific setups where one software is better at than another. I don’t think it is possible to predict it though. What I came across recently is that somebody suggested to fly at different altitudes and also take angled shots as opposed to only straight down:

are you shooting straight down?
I’m find shooting at down 45 degree’s with phantom 3 doing an orbits works pretty well. rather than shooting in the classic grid pattern.
I did one today that worked well, only around 250 photos though, got a high detail model in a hour or so.
now I’m just trying to add another 10000 ground level photos. and then I’ll have another 2000 of so heli shots from previous shoot to add after that. I’ll see how i go with all of these, but I’ll probably run into issues.
and the following posts…
Also the pagefile has been discussed in this forum to some extent - if you haven’t looked already…
Wow, your hardware is quite something - like a new Ferrari compared to my old Fiat…
