As I said earlier Wilson's is a cult thing but I think all custom makers is a cult thing for the people who own a particular maker's gun.
As to fit I think that the guns are very tightly fitted' maybe too tightly fitted sometimes' but probably not any better fitted than any other custom maker's gun.
What Wilson's does have is that they no longer use MIM or cast parts for what they call their bullet proof parts. These parts are machined from bar stock. Also Wilson's bullet proof ambi safety is as good or better than Colt's old ambi safety. No sloppiness at all. And their battle sight is super for tired old eyes with cataracts.
I don't believe Les Baer has ever made use of MIM parts.
