My answer would be to say, 'it depends', primarily on your experience level as a plastic modeler. The Bandai VF-25s and VF-27s are rather complex despite their 'press' together nature. They really work better as glue together kits, but then you need to be careful what you're cementing, as the kits are fully transformable to the three main modes. And there will be seams, and other flaws that can detract from a non painted and non waterslide decaled version, if you do go the press together, no paint, and sticker over decal route. And the instructions do not help much, unless you are familiar with Bandai's symbology and methodology. If you're not, you can easily do something wrong.
While transformable after build, it does require care during the build, and they will always be delicate. This was for the non pro shop version of these kits, by the way.. I have never see a pro shop in person, but they seem very similar to the standard ones, with the clear parts and internal details (more complications). I have been building plastic models for over 30 years, and still found these kits on the challenging end of the spectrum. I've had VF-25s, a Brera VF-27, and a super pack set. My assessment is that unless you're a pretty experienced modeler, they will be a challenge if you want a good, clean, functional build.
