Spacecad v Rocksim

So what are the pro's and con's of both of these titles, what makes Spacecad
more popular than Rocksim in the UK (if it is), and why do you prefer
Rocksim state-side?

I wouldn't say that SpaceCad was more popular than Rocksim in the UK. My experience is that most UK rocketeers use Rocksim. Many of those that don't prefer "lighter-weight" apps such as wrasp, for altitiude prediction.
I use Rocksim myself, I did once try a demo of SpaceCad, and It was OK, but I couldn't see any reason to switch over. I suspect most people are like that, they've been using Rocksim since before SpaceCad was available.

I would have thought Rocksim would be the most popular in the UK, don't think i know anyone whose a regular user of SpaceCAD.
Rocksim is a perfect sim package, easy to back together a quick model and sim it and powerfull enough to get accurate flight data if you give it all the details.
Gets my vote.

There is a UK dealer for SpaceCad (Deepsky), Rocksim you have to order on line. Other than that I would say Rocksim has been around longer and has a larger user base and there are more sim files for it. The only person I know of that uses SpaceCad is Niall Oswald, maybe he could comment on it? I personally use rocksim, as it was all that was around when I started (excluding rasp and the like).

Having never used RocSim, and never a 'real' version of spacecad, I can only offer what I've found with the demo version (I think only printing-type functions are disabled).
SpaceCad is good for throwing together a quick model, and uses ( I think) RASP for simulation, so comes up with fairly standard results. I've come across a few little bugs, but there've been various updates recently I believe. I think SpaceCAD is more suited to models, which is fine for me. Im guessing its also cheaper than RocSim, but less powerful in terms of simulating complex designs. I think RocSim also offers better stability/CD calculations, I'm really not sure though.
Certainly for Estes-type models Spacecad seems good, depends what you want to do with it.
I think (?) Apollo 11 sells SpaceCad, I may be wrong though.
