Quoted from G-P-E:Absolute best crimpers are Certicrimp crimpers from AMP. Those generally start in the $300s and aren't found in a lot of places.
IMHO - best crimpers are the ones with locators such as the Molex HTR2445A (Sargent 3136CT).
I have both Sargent 3136-CT for .156, and Sargent 3135-CT for .100
They are kind of spendy at $110 ea but worth every penny IMO. got them at Great Plains Electronics. Nice tools made in USA!
