I myself use the 05 when I just can't get a setup down for the 415, but the 415 properly setup is a faster car for me. It all really comes down to personal perference and how good you are at setup. That being said the 05 is still a very capable car and with the proper hopups and setup can be very fast.
This post pretty much answers that question perfectly. Just about everyone who owns both says these same things.
