As an oldster, I'll summarize Stansbury v Jans.
Stans's best teams were 2002-2005. Those teams were all better than anything we've had in all the years since except 2019. The 2004 team, despite how they finished, is in the conversation for the best team in MSU history if the season as a whole is considered rather than just the finish.
Stans's years after 2005 were either bad or pretty good, but never better than pretty good. I would characterize Jans first three seasons as pretty good as well.
So yes, at this point Stans has a better body of work than Jans. He had a much longer run, with higher highs and lower lows than Jans at this point. I'd be shocked if Jans run at State lasts anywhere near as long as Stans, but I'm wrong a lot.
