Seems like the G-Lube is more like a 205/105 mixture compared to straight 205g0.
I agree. After about a month of using NK Creams lubed with the G-Lube I can honestly say that I quite like it. It isn't sluggish at all which makes the lubing process a bit easier. The sound signature change from lubing is almost as pleasant to me as 205g0, but the lubing process is less volatile IMO. It's also a lot cheaper and easier to find. Stick with 205g0 or your other preferred lube for your top of the line boards, but G-Lube is great for cheaper builds like the Womier K87 I put together.
