What to choose- CTF set or CTB set? What are their main differences?

In their functions, these sets are similar and have almost the same dies. The difference between them is mainly in the way of changing the dies. CTF has parallel closure of the dies that makes crimping results very good and reliable. Unfortunately, the change of dies can take some time, as the user needs to unfasten two screws to change the dies. Change of die in CTB takes only a few seconds. The crimper is designed for possible crimping with both hands. It is also worth saying that CTB crimper is one of the best choices on the market, thus very popular among users.
