Developer for Arista Private Reserve RC photo paper

I would like to know if anyone is using Arista Private Reserve black and white RC photopaper available from Freestyle. I have heard conflicting opinions and debate about whether this is a rebadged ADOX MCP or Kentmere paper. Can anyone shed some more light?

Can I use Ilford Multigrade liquid developer to develop this paper? I have heard that Agfa/ADOX MCP paper works better with Neutol developer. Is the result significantly better? I would like to keep using the Ilford Multigrade developer that I have in stock if possible. Any advice or suggestion is appreciated.

The Multigrade developer should work fine.

Other developers might give you slightly different contrast or image tone, and may result in a slightly different response when toning, but generally those are differences of preference, not function.
