Soft scans from Epson V750?

I’ve just been reading Jack Flesher’s account of his first impressions of the Epson V750 compared to the 4990 (soft scan but better dmax). As I was just about to buy a 750 this has made me wonder whether I might not be better off with a 4990 after all.
I shoot colour slides, more 6x9 than 4x5 until now.
Has anyone else had the same or different experiences to Jack? I’d be most appreciative of any help. In addition, as I haven’t got any software, do you think it’s worth getting a package which includes Silverfast Ai and Monaco color or not (e.g V750 rather than V700)?
Thanks,
Mike
