Hi there - on an upcoming project I will need to use a CAN controller.
I have previously used the Microchip MCP2515. What other CAN
controllers are there out there? All I know of is the NXP SJA1000. Any
opinions on advantages of one over the other?

By far the biggest advantage to be had is to use a CAN controller integrated with a microcontroller, not as a separate chip. Stand-alone CAN controllers will take considerable resources just to connect them to the micro: read/write message box control and data registers, route interrupts, do access control and all that. CAN itself is just two wires taken care of by the CAN controller. A lot simpler.
