you sure that scorpions are more durable? statistically you need 6,75 hits to destroy one scorpion or 4,5 falcons... 5 falcons cost the same than 1 scorpion, so i would consider falcons at least as durable as the scorpion...
Durability isn't just about destruction. You have to consider partial loss of the formation, suppression and breaking. War engines have advantages in all those comparisons.
So, as an example, compare 3 AT hits on each formation (just because the math is easy).
Falcons average 2 kills + 1 BM, usually breaking the formation in a single volley. When the Falcons rally, they will have 40% of their original firepower (3 units, 1 BM = 2 firing). If they get lucky and only have 1 kill, they are still at 40% of their firepower (4 units, 2BMs = 2 firing), 60% after a successful rally.
Scorpions average 1 1/3 points of damage, so usually the Scorpion will take 1 point + 1 BM, remaining unbroken and with full firepower. If it takes 2 points and breaks, it will rally back with 100% firepower compared to the Falcons' 40%.
There are also some non-quantifiable issues to consider. 45cm range is in assault distance of fast units if the Falcons cannot hit-and-run, while 60cm is not. The 60cm range on the Scorpions' weapons give it almost double the amount of area to find terrain for pop-up attacks and it needs less cover because it is smaller. Those advantages are minor and dependent on good play but they are relevant.

BTW, I agree the Falcons are the better choice overall. The are ahead both as pristine formations and as heavily damaged formations (because the Falcons are likely to have a straggler survivor that can run around being a nuisance, while the Scorpion would probably be completely destroyed).
I'm just saying it's not a "no brainer" that the Falcons are far better.
The two formations are definitely a lot closer now than they were prior to the 2008 rules mods, when Scorpions were the only sensible choice.
