Trying to answer which kit is best is a bit like answering 'whose wife is best?'. The fact that we chose our wives means they ARE the best in OUR eyes. If anyone would like to nominate a different wife then my argument has a flaw!
When someone tries to tell you why their wife is better than yours it is obviously to going to raise blood pressures and raise what we would quickly see as a totally pointless, subjective discussion. Why we cant see this is the same here leaves me a little bewildered. I used to hear this back in the UK, which is better, Gardner Douglas, Dax, Crendon etc. Same discussion here just different manufacturers.
The fact is that all the kits and manufacturers mentioned are trying to create emulations/replicas of a car that hasn't been built for 40+ years. So, removing the emotion and subjectivity from the question unless there is an EXACT replica, which I am not aware of, then ALL fall short to some degree and what is left is prioritizing one shortfall over another. i.e. do you prioritize exact dimensions and body style over interior quality over track performance...and so on.
There was only one source for the real thing, it is gone. All we are arguing over is which copy is better than another copy. Lets forget that and enjoy them for what they are...copies!
I know I enjoy my copy!
