An LC40 is as good as it gets. Fantastic machine.

4-axis means you can program the two turrets independently - both can be cutting at the same time if you want, or one at a time - it's up to you. You control how the turrets synchronize their moves with program P codes.

This opens up a whole world of possibilities. Both can turn at the same time. One can turn while the other bores. One can turn while the other faces. One can act as a steady rest while the other turns. One can be positioned to start cutting the instant the other finishes. And so on.

Of course, the workpiece and your tooling will dictate what you can and can't do with 4-axis, but it can get pretty exciting.
