My two cents: Eduard's Dora kits are definitely complex but I'm personally a fan of the attention to detail. The fit issues that arise stem from the more-than-usual amount of parts that need to line up perfectly. There is an increased need to plan ahead and to dry fit and adjust parts to make things come together properly, but if one is careful, a good fit will result.
In my opinion, the Eduard kits I've built are unmatched in quality of surface detail and I favour them over the Tamigawas.
