For baselayers? I've tried all sorts (though not icebreaker) and Rapha have been the best by a margin. I like them soft and loose-knit/flexible so they cling and insulate just enough. Polyester is horrible when next to the skin and wet.
For jerseys polyester and polyester-lycra mixes have it all covered being better at getting rid of sweat (coolmax and lycra-mixes), windproof (both the lycra-mixes and the layered polyester used in winter-weight jerseys), quicker drying (all types) and less bulky (all types – especially when wet). I've only tried Rapha sportswool jerseys.
