Lately I've been using the Arcteryx Alpha SV glove, mostly just the outer gtx shell without the liner (the liner is nice, but skinning up I run hot and going down I don't need as much hand warmth in the PNW. The glove is versatile enough to do rope work. This glove is not warm enough for really cold weather.
Previously I used a modular system by OR - gtx mitt shell without any padding / insulation, and then fleece mitt liner and / or wool glove liners of different thickness, as needed. Worked great for our wettish weather but mitts are not as good for knots and such.
I tried Black Diamond Pursuit gloves - great dexterity and breathable shell but got soaked in our spring conditions, so I'm not a fan and wouldn't recommend for splitting.
Kyle Miller splits with 2 pairs, the Petzl belay glove for skinning up, and another set of gloves but I don't remember what.
