This is the easiest series to predict; Avs win in six if goaltending is average, Jets win in five if Avs goaltending has been what it has been this season. Lol.
The Jets can play against the Avs quite well, but some of their wins were sort of flukey like when MacKinnon was out for one or two of those games. I don't think the regular season will showcase the disparity that happened, Avs will raise their game and I suggest that Bednar is competent enough to figure out what went wrong and make adjustments.
This doesn't mean I am undervaluing the Jets ability to shut down teams though, Lowry is one of the best in the league and will get to play a lot against MacKinnon due to having home-field advantage. I very much respect that ability and factor in Hellebuyck who quite easily is a top 3 goaler in the league. With that said, I do think Avs possess superior depth throughout, especially offensively. Has that shown up lately? No, not really, but I give Avs the edge in that ability on paper, I could see the Jets defensive core as a unit struggling against Avs speed, ferociousness, and talent to roll four lines one after each other. That doesn't mean the Jets do not have options as well, and can absolutely expose Avs defensive issues as well along with potentially super poor goaltending. That's exactly what they did during the season series, but again, Bednar is no doofus, he likely knows how Winnipeg won all the games and will come up with a gameplay against that. The problem then comes back down to goaltending where if Avs can overcome leaky goals constantly...so that question is a no.
