Looking for lens advice - Lumix G 25mm F1.7 vs Sigma 30mm F1.4 DC DN C

Im looking to expand my kit a bit for some sharper images and better low light performance. I shoot mostly nature, some landscapes, events, nothing in particular. I almost never shoot with my kit lens on the wide end, im almost always zoomed in at least a bit.

My current kit is added to this account, and I already intend on buying a 42.5/45mm prime, most likely the Lumix G 42.5 f1.7 for its closer focusing distance (in place of a dedicated macro lens for now)

But I'm on the fence about my second prime. I know that the Sigma 30mm 1.4 is statistically a sharper and faster lens with a more usable range of apertures with minimal distortion, my thought is that its so close to the 42.5 am I just wasting money or will I even bother swapping lenses for that small of a difference? Dont get me wrong, the Lumix 25mm is inexpensive and has decent ratings on Dx0 but the acutance map looks awful until about 2.8 where its mostly in the green, and the vignetting is pretty bad until 2.8 as well.

Can any of you guys who have been in this situation or who own the Lumix 25mm comment on its sharpness or your thoughts?
