Functional Difference between Packaged version of carla and full build

[TylerParzialeCat]

I just began experimenting with CARLA for simulation and in doing so I went with the easier option of downloading the packaged version and following the tutorials to get the extra maps and assets.

I've slightly played around with making my own scripts to track certain actors and variables and am looking at moving to downloading the full build. However as of 3 days ago Unreal seems to not have a stable build to accurately set up , and aside from designing maps, what benefit does the full build give that the packaged version does not have? Is it just the use of Unreal with Carla or are there more features that are crucial towards editing and developing within Carla?

Edit: and also if anybody has a fix for the current Unreal engine being unbuildable that would be momentous
