I've used Deans and the TRX plugs. I prefer the TRX plug because you can solder up to a 10g wire on it, and its has bigger contact area then a Deans. You do need a good hot iron to get a good joint, sometimes the solder will go past the 3mm mark. If that happens a dremel can be used to take off any solder blobs. Really after its put together it should not be taken apart ever again unless its worn and getting replaced by a new one.
