It depends on what your needs are. The first,

activecell.Formula="=sum(a1:a5)"

will insert a formula, so its result will change as the values in
A1:A5 changs.

The second,

activecell=worksheetfunction.Sum(range("a1:a5"))

will return a number which will not changes as the values in
A1:A5 change, unless of course you re-run the code.

Without further detail, I would likely use the first approach.

among these two code statements which is better

activecell.Formula="=sum(a1:a5)"
