LOCAL.RAND=<EVAL {1 1000}>
IF (<LOCAL.RAND><=5) //0.5% Chance Loot Drop

has the same results as

IF (<R1,1000><=5) //0.5% Chance Loot Drop

which is the same as

IF (<R><=5) //0.5% Chance Loot Drop

...except that in these versions, there less for the server to do since there is less script to parse, no allocation of memory for the temporary local string variable, no evaluation of the random {}, no assignment of the resulting integer to the string value, no re-evaluation of the string back to an integer in the if statement...

To be fair however, this all takes place in microseconds.inside a @Death trigger that does not get called all that often. :-)
