The chances are that people will recommend the awning they have. I think they are all much of a muchness & you would be better choosing one that has the amount of space that you need.
I have a Vango Kela Air awning which is very good, but I find that I rarely use it because it is so bulky & takes up too much room in the van. I tend to use my Sheltapod 90% of the time.
Depending on which Fiamma canopy you have, you can add sides & front to many of them.
Wanting room for storing bikes, or putting the portapotti in, or sleeping in, is a reason for getting a drive away, but they’re bulky and heavy, which is why we never got one (though we looked at plenty at shows & online). The chief thing to look for is the height, as the tent door flap will have to go over the top because of your awning rail, I think.
For defining your sitting out area, on a crowded site or where you’re on a shortcut, the wind-out awning is plenty big enough.
