Fuji 27 f2.8 vs sg image 25mm f1.8

I own the XM5 with the kit lens and I have the first version of the fujifilm 27mm f2.8 pancake lens.
Due to the lack of ibis, the f2.8 is not that useful in low light (besides this and the slow AF motor i really like the colors, form factor and everything else of this lens).
I've placed an order on the 25mm f1.8 sg image and I'm curious to see if it's worth it or should I cancel it.
