For the OP, because it focuses on category rather than brand, this is a very helpful reply. And it's a fair summation of a system which works well for me. in my case this would mean:
Brynje mesh tee (yes, they really are incredible)
ME Eclipse microgrid fleece with integrated hood/balaclava (only the Patagonia R1 comes close)
Arcteryx Squamish windshirt. Superior adjustable cuffs for significant extra comfort (I suffer badly when overheating) make this the pick of the bunch. At a price.
Patagonia Kniferidge softshell Jacket in Polartec Powershield Pro (a compromise between waterproofing and breathability that I'm experimenting with). Alternatives at my disposal include an ME Tupilak Goretex Pro waterproof if it's tipping down and a Montane Alpine Stretch softshell for blue skies.
North Face Makalu belay jacket with 130 fill Primaloft Pro means substantial warmth on the belay
Just a word for the Patagonia Nano Air which has been mentioned once already. This hoodie combines the role of midlayer and windproof in all but the wettest conditions and, with its incredible breathability, is the most versatile garment in my wardrobe. There isn't a month this year when it hasn't been useful as it's fantastic for rock-climbing (short bursts of effort followed by a longer spell of inactivity in exposed locations). For a typical Scottish grade II classic ridge (Aonach Eagach, Forcan Ridge), where you keep moving a higher proportion of the day with only short stops for individual technicalities or photo ops, or for a winter day's walking, there is nothing to beat the comfort this jacket provides. And on such days the Nano Air worn over a tee shirt will suffice. For your stops, worn under a wind or waterproof it is all the belay jacket you need.
I hesitate to recommend it as an outer for winter climbing, though it holds up well for rock, because water penetrates the outer too easily, but on frigid days it could replace both fleece and windproof and then layer under your shell (or even under your windproof and drop the soft/hardshell altogether if the forecast allows you to be so bold)
