Yes, having one core at 2x clock is definitely better than having two cores at 1x clock, I'd agree with that. These days however, the difference between fastest core performance on low-core processors and fastest core performance on high-core processors is rather a lot less than 50% (Comparing like for like, eg AMD to AMD and Intel to Intel).
