Best DSC pointing model

Of the various DSC computers, is there a real difference in how easy they are to perform alignment, and how sophisticated the alignment model is.

For example, with a very rough polar alignment, my G11/Gemini doesn't need the initial OTA aim to be precise, but the Argo Navis manual says that the OTA should initially be accurately aimed to be perpendicular to the polar axis or accuracy will suffer.

Among them, are any notably better at developing an accurate pointing model that includes real-world imperfections in the mount such as non-orthogonality and backlash over the meridian?

Finally are there computer-based (either hand-held or laptop) solutions that are better?

I look forward to your replies. Thanks.

The Sky Commander uses a simple two star alignment and does not require a preset position for the tube. There is no warp factor to contend with either. Just set the date and then choose a star from the list point it to it and then repeat for the second star and your done.

I use the Pocket Sky with my Tak EM200 Temma 2 mount and find it the easiest alignment program I've used. I just polar align with the scope, unlock the clutches and center any object in the sky, select the object from a graphical interface on my IPAC and then select "Synch" and I am good to go.

I do use Sky Commander on my Starmaster and find it to be quick, simple and almost always gives me a good alignment the first time.
