Default 5052 vs 3003

I'm trying to get some data on the two alloys with respect to shaping and the properties that are important to shaping. 5052 is readily available to me but it seems 3003 is the alloy of choice for most metal shapers. I've only used 5052 for any shaping projects. I usually use 0.060 inch but I have gone up to 0.080 inch on occasion. I use TIG welding for joining and have found I can make nice ductile welds using 5356 as a filler. I've also been able to get the shapes I want though may have to anneal on parts that have a what I consider a lot of shape. It seems that 5052 is a bit more corrosion resistant and seems to be a bit stronger if it's work hardened. I've also read that 3003 can be easier to weld but I'm not having any serious issues with 5052 and 5356 filler.



So, to get to the main question, if I'm getting the results I want already with 5052 are there any compelling reasons to search out a source for 3003?

3003 vs 5052
5052 is double the strength +.
5052 is marine grade aluminum, used on US Coast Guard cutters, fishing boats, etc. And on airplanes.
3003 is easier for some folks to weld, but 5052 is a non-issue for most welders.
3003 is a little more workable than 5052, but both alloys make nice parts - tanks, door skins, wing tips, wing parts ... etc.
