The images as supplied by the manufacturer in this case Vu+ is as basic as they come, it is simply intended to provide a working image while keeping on the rite side of the law. hence no official support for softcams etc. as for the teams you listed above they tend to fall into two categories.
1. OI Based. ( OI = Official Image ).
This is BH ( Black hole ) and VTI.
2. Pli based ( pretty much every one else but this is a fast moving area of development ).
now while officially teams such as ViX and ATV will be listed as Pli based they are in fact members of the OE-Alliance which it self is moving further and further away from Pli, for example the new OE ( Open Embedded ) Build environment used by the OE-Alliance for arguments sake lets call it OE-2 is no longer based on Pli's OE but a complete new build from the ground up, although some teams like ViX still do from time to time merge with Pli's master feeds for bug fixes etc.
ok so thats the long and boring part over, basically all images do the same thing but with their own twist, ViX are well known for their ( wife friendly ) images ( that even the wife can use ) and their EPG, which in the uk at least can't be rivaled by any other team. My best advice is to try as many images as you can and settle for the one that best suites your needs, but make a few backup images along the way, so if you ever need to switch back to a earlier image you can do it in seconds.
