different years and models of Suntour deraiers may position the top guide pulley closer or further from the sprockets, but as long as you can work within the derailer's range of adjustment to get a gap of around a quarter inch, both should shift really well.
Note that there needs to be clearance between the outer cage plate and the cogs as well, which can have some effect on the gap you might be able to adjust to.

Some models also have stiffer springs than others, but in general, Suntour return springs aren't overly stiff.
