Macro substituion will be faster because execscript has to write the code to the disk, compile it and run.
Here's a test

lnMax = 1000
lcCmd = "lnCount = lnCount + 1"

lnStart = SECONDS()
lnCount = 0
FOR i = 1 TO lnMax
	&lcCmd
ENDFOR	
? "Macro", SECONDS() - lnStart, lnMax, lnCount

lnStart = SECONDS()
lnCount = 0
FOR i = 1 TO lnMax
	EXECSCRIPT(lcCmd)
ENDFOR	
? "EXECSCRIPT", SECONDS() - lnStart, lnMax, lnCount

Result:
Macro - 0.01 sec
Execscript - 16.8 sec
