Corrosive will do more damage than Viral if the target is a Ferrite armored target. This is because Corrosive will both "ignore" a percentage of armor in the calculations as well as deal bonus damage, while Viral will only deal bonus damage. Of course, that also limits your damage bonus to Ferrite.

Radiation is the same as Corrosive but for Alloy.

Thus the only thing that really makes Corrosive stand out is the -armor proc. Whether that proc is worth building towards is up to you.
