This has worked for me coming from someone who's coming from a warm climate to blistering Midwest winters. Snow
Temps around 15 and lower
PL-J1, C1-AJ, NG4, P39-PR under P44-GT Cold
20 & UP
S32-PX, J25-WS*, NG4, P24A-DS
*Sometimes if I want a hood I'll wear J25 under it since it's thin and I don't get that clammy feeling.
GT-J16, S13-W, P10A-CH
For me, I've found value in ACR knits. They keep me warm, quality, and haven't had any issues with QC or function. Pilling hasn't been crazy either so it's giving me that quality feel. Ideally, for what I wear I'd like more lined items, so P38-AD would've been better than double panting but that's for another time. End of it all, I think if your baselayer is well thought out then the ACR is secondary.
