Yes and no. If you use a 130 with a binoviewer you lose brightness on Deep Sky objects. With two 100mm objectives using two eyes, you reduce the noise (floaters etc) as your brain does an automatic unsharp mask and noise removal. Your vision is relaxed using binocular vision, so you tend to pick up contrast more readily and resolution is improved. So your 100mm OG's will probably be about the same as a 150mm telescope using a binoviewer.
