Not all FT-847's are alike. A stock FT-847 has wide, low-Q ceramic IF filters. My FT-847 has INRAD CW and SSB crystal filters that give narrower IF bandwidth, with MUCH higher Q. I haven't compared them, but I suspect that a FT-847 receiver with quality IF filters performs roughly on par with an IC-910.
If shopping for a used FT-847, look for one with optional IF filters. Collins mechanical filters are an improvement over the stock ceramic filters, but crystal filters are even better.
