As long as you want to stay free of fairings, I would have to think this is a better option than a clapped out, potentially cracked salvage frame/etc. Obviously, all of the attachment points for OEM stuff are probably not going to be there, unless someone with a welder decided they wanted it to be in place. Does the OEM tail section bolt on where it used to? Does that carry the battery, ECU, R/R on your model?
Any idea where the wiring harness should route? (it would be really cool if you could use the inside of the frame for that....)
The steel will likely be heavier than the aluminum, but a heck of a lot more durable. It really comes down to how well they brace the thing where it matters -- at the steering neck, and in the area of the swing arm pivot. Trying to keep those two points in the same spatial relationship as they have at a standstill, is the art of frame construction.
In the 1970's Triumph used one really big tube to connect the swing arm pivot area to the steering neck, similar to what Confederate is doing with their bikes -- if the tube is big enough in diameter, it will be stiff enough to maintain the location of the steering neck and swing arm pivot.
The whole reason that the twin spar frames were developed was due to the increase in power, and traction that started twisting the simple steel frames so much that they became evil handling pigs at the limit.....
if it's meant to be a street bike in moderate use, I'd think a stunt frame should be fine for that.

"There's this adage that we have 2 ears and one mouth so we should listen twice as much as we talk. Unfortunately with the Internet people have taken this old adage and turned it around. They have two eyes and 10 fingers so they think they need to post 5 times as much as they read. And since they have 10 fingers and one brain, they only have to think 10% of the time! "
