Electrical solderless or soldered connectors

I use solderless barrel crimp connectors with heat shrink over the top and I crimp them with the proper crimping tool. Never have a problem. I absolutely hate butt connectors or any type of connector with an insulator that you crimp through. Solder will weaken and crack over time with vibration and is not fool proof.
Thanks, I did find that fit you solder only the tip of the wire in the connector, it does not crack, but if I solder the connector and wire leading into the connector it will crack. I need the push on female connectors. I hate crimping them over the plastic. And yes, I do have the proper crimpers. that is what is so annoying, sometimes when I crimp them properly it still cuts the connector from the wire
