I'll be "that guy" on every RC forum everywhere, and toss the "Crimping" grenade into the convo:
In terms of connections: a REALLY good solder job>Crimp>a poor solder job.
Crimping is mechanical, and a lot harder to screw up. It's also easier to crimp connections in the field, and in the model (not a lot of fun removing an ESC buried in a foamy fuselage on an airplane, just so you don't have to worry about the soldering gun melting anything
I use anderson power poles in my trucks, planes, and boats. Even my 6-cell Arma Talion is happy running on them.

Note, many folks see the various sized pins labeled by amperage (eg. 30 amp connector), and presume they can't handle more amps then that. It's not true (I know for a fact and from experience). Essentially that's the amperage they can handle for prolonged periods of time in environments with zero ventilation (eg. industrial applications).
Cons:
-they're somewhat expensive
-the APP crimping tool is cheaper than a top shelf soldering iron, but $40 still a lot for a specialized tool (worth EVERY penny though)
Pros:
-Ask military aircraft mechanics how they make electrical connections

-it's a lot easier to get a PERFECT crimp, than it is a PERFECT solder job.
-no solder fumes.
