Absolutely tougher usage. Ekholm pairing has always been the prime defensive matchup pairing for Nashville, not the Josi pairing. In Toronto, it's always the Rielly pairing.
And let's not act like Nashville has been some sad sack team before this year. They were not - and you can't say rielly's offense is boosted by his team without saying Josi's defense has been boosted by his.
As for PP - due to Babcock, Rielly received much less Pp time than josi did before this season. Not to mention he gave his #1 pp spot to Barrie last year.
And really, the 3yr sample kinda glides over the fact that Josi had one massive offensive year and Rielly one bad one. Rielly's solidly more productive in most years since he's entered his prime.

True of Ekholm but also true of what Muzzin is to Rielly, would be curious to see their o-zone vs d-zone starts.
Here's your numbers purely for offense, again not a great way to analyze a defenseman as much as it is for forwards, you're also purely looking at offense here, nothing to do with defense for defensemen:

Looks to me like Rielly is the one who had one massive offensive year in 2018-2019... His 20 goals (11 more than any of his other seasons) where his shooting percentage of 8.97% is
271% higher than the rest of his career at 3.31%; that one year boosts his career shooting percentage to 4.88%. Josi's shooting percentage has been consistently high: 7.81%, 5.21%, 7.74%, 7.46%, 7.07%, 5.53%, 5.53%, 5.47%, 6.15%, and 2.53% as an outlier in a much smaller sample size (25gp) this season. His career shooting percentage is
6.13%. I'm assuming you thought Josi's one massive year was the year he won the norris trophy in 2019-2020? His 6.15% shooting percentage that season is a whole
.33% higher than the rest of his career at
6.13%!
