The Hyaku-Shiki is a timeless kit, with a classic design that transcends time, series and model kit range. The latest iteration of the Hyaku-Shiki - coincidentally also Bandai's 200th HGUC model kit - updates the venerable golden mobile suit with modern Gunpla technology, features, gimmicks and ease of assembly.
The Revive version of the Hyaku-Shiki is a tad smaller in stature than the older version, but has superior articulation in every aspect. A gripe I have is that the kit doesn't come with trigger hands, only the normal saber ones, resulting in the Hyaku-Shiki gripping its weapons below the trigger. However, this is an easy fix: Builders Parts are your best friend.
Bonus: the Revive version of the HGUC 1/144 Gundam Mk-II is TIGHT.
