I find that getting the wires lined up is easier with the standard connectors - and you don't need a special crimper. Keep in mind that the count of RJ-45 connectors that I have terminated in the past 40 years may well be a 5 digit number (over 10,000). I can damn near do then in my sleep.
Now if you really want to get the best of both worlds, for Cat-6 connectors, there is a little insert that holds the wires in position. So you thread the wires through the insert and cut them off. Then the insert with wires inserted get shoved into the connector body and crimped. It's done that way because to meet the Cat-6 standard, the wire twist needs to be maintained to within 1/4 inch of the crimp. Can't do that with a Cat-5 connector.
And before someone gets too picky, the connector we use for LOR, DMX, and Ethernet is not a RJ-45 connector, but actually an 8P8C connector. But if I called it that, most people would have no idea what I was talking about.
