Full Kurama would boost up the chakra reserve and make Kurama's chakra more powerful as Choji commented how powerful the cloak was when both Yin and Yang Kurama chakra was given to them compared to just Yang Kurama. Also with more chakra, Naruto can pour more chakra into his attacks to further increase their power. His overall stats would all be increased as well (speed, strength, endurance, stamina, durability, power). Then you add Senjutsu to that already powerful chakra and it becomes even stronger.
Yang Kurama alone allowed Naruto to match 5 Bijuus combined tbb so half Kurama is already shown to be powerful, add in the other half and Kurama should be stronger than all 8 Bijuus but then you're adding natural energy to the mix to make a new and more powerful chakra out of the already powerful chakra. So yes Naruto would be much stronger than he is now and how he is now look to be close to Sasuke so I put full Kurama over both of them as they are now.
