Can't comment on Revell or Hobbyboss (can't find a 1/48 Vb listed under those brands at Scalemates). So that leaves either Tamiya or new tool Airfix.
Tamiya
- guaranteed good fit and enjoyable build
- decals will likely be thick
- shape wise it has been described as 'short, fat, slab sided and the wing shape is too broad at centre chord'
Airfix
- more accurate, but details not quite as refined
- some build problems, particularly fit issues with landing gear and armoured fuel tank in front of cockpit
-------------
Another option is to wait a bit for Eduard's 2021 release schedule. Currently have new Spitfire Mk.I and II, so there is reason to expect a follow up with a Va and Vb.
