The right style of awning depends a lot on how you camp. If you are more a traveller or hiker that moves every day, then being quick to deploy and retract is most important, and the Fiamma is definitely miles ahead in that regard. If you are more of a base camper who goes to one spot and camps for a couple of days and stays with the camper, then the wrap around awnings with the most shade may be a good idea.
We are rarely by the camper during the day, and mostly spend one and at most 2 nights in one spot, so for us the Fiamma makes the most sense, and I even remove that in the winter when it is just dead weight.
A camping buddy has an ARB style bag awning on his van, and neither he or I are impressed with the bag style awnings. The same or less shade than the fiamma, 2-3 times as long to set up and take down and even longer with only one person. It is also much more sensitive to wind.
