Can't hurt to call the SPG toll-free CS number and ask if they will match it. I agree that SPG (Starwood Preferred Guest) is a better program.
...because I have about 12,000 miles each on 4 other airlines that I will never fly again (TWA, DELTA, UNITED)
Never say never, especially if you're travelling a lot! You could get bumped to one of those airlines with a cancellation, or you may find down the road that some fares just may be cheaper on them. You should also have a back-up just in case your preferred carrier has a problem.
