Compare: Rocket R58 vs. Rocket Hx Espresso Machines

For years now, we have had a deep and abiding love for Rocket Espresso's heat exchange machines, so when their new dual boiler model, the R58, hit the market, you know that a dance party ensued. But aside from sharing some of the aesthetic principals of its Hx counterparts, how does the R58 compare? And why would you choose one style of machine over the other? In this video, Gail does us the sweet favor of breaking it all down for us. She talks about functional and feature differences, why you'd want a dual boiler or a heat exchanger and then crafts cappuccinos on both styles of machine to demonstrate how they compare, performance-wise.
