The case for an existing battery owner
DCS590B makes its clearest buying case when suitable DeWalt power equipment is already available. You can add a mobile saw without treating a whole new platform as part of the project. A first-time buyer should instead price the saw with the appropriate battery and charger. The fitted pack also changes the size and handling of the complete tool, so the bare saw body is not the entire comparison.
Capacity and accessory decisions
The manufacturer documents a blade-right 7-1/4-inch format, electronic brake and 2-9/16-inch depth at 90 degrees. Confirm the bevel-cut requirement separately and choose an appropriate blade. Dust collection requires the correct adapter and extraction arrangement; a photograph of a port or a generic accessory description is not enough to establish that the required parts are included. Customer comments about finding adapters are purchase questions worth checking, not instructions to improvise a connection.
When another saw is a better fit
DWE575SB can be a rational alternative at a powered work position. Makita XSH03Z is a smaller-blade comparison for suitable LXT work; it should not be selected when the actual stock needs greater depth. Manufacturer cuts-per-charge figures depend on the specified pack and test conditions. We have not repeated those tests or compared runtime between brands, so they should not be used as a simple ranking of everyday value.
