Having ridden both Shimano and Suntour 7 speed indexed bikes back when that was the newest thing, I can confirm that Suntour indexed 7 did not shift as buttery smooth as Shimano, but did not jump out of gear unexpectedly. Rather, even with indexing, one had to occasionally overshift (with Suntour Command Shifters) to get the chain to move to the next cog when downshifting.
