I'm really not a fan of XT-series connectors, and solder-type connectors in general. It's much harder to judge the quality of a solder joint than a crimped connection.

In my experience using these connectors with stranded wire causes solder to wick up into the wire a bit, causing the wire around the connection to become brittle and prone to have issues if not given adequate strain relief. Soldering in general is much more error-prone and time consuming than crimping a connection with the proper tool.
