Jamis Renegade vs specialized diverge

Louisb_11

I am about to pull the trigger on a renegade exploit 2018 https://m.pinkbike.com/buysell/2529625/

But also could get a specialized diverge tiagra 2018

I basically want something for gravel events, light bike packing and the ability to put on road slick and roll along nicely. Any recommendations? Any preference with steel vs carbon or 105 vs tiagra?

Any advice would be awesome
