The comparison would be

a if then else end if .. about 8 of them 2013-> and a static insert into 

v's

making a dynamic string and using execute, my presumption would be the execute would be expensive verses a INSERT command

Assuming you're not doing anything particularly crazy it's minimal.
But what is good performance for one application may not be acceptable
for others. Generally the cost of inserting is MUCH higher than the
cost of dynamically setting the target, esp if you stick to plpgsql
and don't try to use rules to accomplish it.
