Technically it's a truss frame by virtue of the extra tube between the seat tube and top tube, but most bike mechanics would recognise it as "a piece of shit". The odd geometry makes it vaguely resemble a full-susser, but serves only to make the frame weaker and heavier.

Take away the extra tube and the kink in the downtube and you're left with a classic step-through frame.

A "fashion" frame. It's functional to an extent, but it is needlessly complex, as evidenced by being both a truss frame with a pointless bend and not the convenience of a step through frame.

I'd recommend a tourer frame if you ever expect to carry or tow weight, and any other kind of simple frame if you want to get about. That kind of fancy frame is going to get you from A-to-B and any bike that gets you there is a good bike, but you can make your life easier by getting the proper tool for the job.
