I like both Alpen Lights and the Hi-Fi bars. I find the Alpen Light flavours tend to be a bit more breakfast-y, whereas the Hi-Fi bars seem like more of a treat, if that makes sense? Most days for my HExB I have one of the fruity Alpen Light bars for breakfast (Cherry Bakewell is my favourite!) and then have a Rocky Road Hi-Fi bar with a cup of tea in the afternoon when I'm craving something chocolate-y.
