The Toney fight was by far Jones' most impressive win. At that time, Toney was considered the #2 PFP fighter in the world, trailing only Whitaker.

The Ruiz fight gets extremely overrated by Roy fans. That was only a big deal because it was interesting to see a smaller guy fight at heavyweight. But everyone expected Roy to win, because Ruiz was a stiff. He was a champ in name only.
I think Roy's win in the first Tarver fight (and yes, Roy did win that fight) is more impressive than the win against Ruiz.
