MAC Barbados Girl Lustre Drops ($20.00 for 0.60 fl. oz.) is described as a "rose gold bronzer." It is a warm-toned, coppery bronze with a frosted shimmer-sheen. Blended out, it will add a coppery warmth to the skin along with flecks of golden copper shimmer and sparkle. Illamasqua Supernatural is slightly warmer/darker but still similar--it is a cream formula, so it is also more similar than a powder product would be. MAC Sun Rush is lighter, more golden, less coppery. See comparison swatches.
