[Closed] Noro A1 Threshold or Planet X London Rd?

Right, my Genesis Croix de Fer is rusting away after three hard winters of commuting and most parts on it need replacing, it makes more sense now to get a new commuter! I don't want to spend more than I have to and given the rust on my steel frame I think Aluminium is the way to go this time. Looking at what is available both the Norco Threshhold A1 and Planet X London Road are under 1k. Both have decent specs, the Norco being mainly Shimano 105 the Planet X SRAM Rival. I have no experience of either brand so can anyone offer any opinions on the two bikes?
