I have Dusty in Memphis, it's a pleasant, well crafted album. As far as her 'Northern' stuff goes, I have to say I prefer 'What's It Gonna Be' by Susan Barrett, another white popster, not because of it's rarity, I just think the whole package is better. Dusty's Bacharach-David stuff is excellent pop music, if you like that kind of thing. Smokey? I think most of us would acknowledge the fact that William Smokey Robinson has cast a huge shadow over the whole music industry, all genres. The man is truly versatile: Producer, arranger, writer, musician & yes, a great, great Soul vocalist. It's probably a question of taste again.
In general terms, I prefer the 'If You Don't Know Me By Now' style of delivery.
I couldn't stand (& still can't) the Stylistics & hated I 'Hey There Lonely Girl'. I think Eddie Holman is a great vocalist, except when he goes all high pitched on me. Smokey's vocal isn't the classic falsetto, it has an ethereal quality, which when given the right moment, can floor you right there in the living room. When I was 13 or 14 years old I used to listen to my sisters 45 of "mirage" over & over, memerised. Lyrically it's faultless & vocally it's extraordinary. Finally, & with all due respect, I think the comparison we're being asked to make on this occasion is slight dubious, even spurious, but then again the Spaniards have an expression that says ALL comparisons are odious.
