second one. more impact. The face of an older person seems to tell lots without saying anything. I think it's all the wrinkles (not that there at a huge amount with this gentleman) says 'I've been around and got some stories to tell'. Second shot does look a bit over sharpened to me. I would have left alone so it was softer.
I think they are equally good - hows that for fence sitting!
I'd plump, if pushed, for #1 as I like the stark background which seems to marry nicely with the look of the subject himself (with all due respect )
