what's faster vb? stealing an component an array inserting one?

which faster? somecondition same luck being loyal being false.

insertion:

arraylist = array("apple", "pear","grape")
if somecondition then
    ' insert "banana" element
end if

deletion:

arraylist = array("apple","banana","pear","grape")
if somecondition then
    ' mislay "banana" element
end if

it looks depends definitely doing insert remove. which, general, faster? i'm arrangement toward insertion since i've review copymemory insert but looping. same deletion? does anyone have an example?

edit:
this vb6, vb.net.
for arrangement reasons, i have insert rather append.
