Based on past editions, I thought Signpost was really solid. But with recent change to the syllabus, all the old books have been overhauled with new modern layout/typeset - and they all look good. I only have seen (yrs 7 to 10) of Insight Maths (now published by Oxford, authors Ley & Fuller) which visually look modern with lots of crisp modern graphs, diagrams and illustrations, very much like all the other publishers.
