The 30 has more weight resistance but the 45 has a more flexible weight stack because the first plate is not as heavy as the rest. The 45 comes with a preacher curl attachment, a cover for the weight/guide bars, and the guide bars are not sectional, therefore the machine has to be freight delivered to your door, you cannot pick it up at the store, meaning big shipping fee.

Looks like the other one has a cover that covers the weights where the 30 does not. It may also come with a few extra things that the 30 does not come with. I would watch the videos....

A few pieces of plastic that make the xr45 look more aesthetically pleasing

looks like the 45 has a cover over the weights, and may come with the preacher attachment.
