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.
