Juri was my secondary in Street Fighter 4. She was wild and chaotic and wasn't a complete chore to learn. They changed too much with her in Street Fighter 5 for me to bother. I did like how her Pinwheel Kick was changed to be more anti-air, though. I probably could have tried harder to learn her, or anyone else for that matter, but once I got the hang of Falke, I didn't see the need. If they get her back to what she was like in the fourth game, I'll likely give her a go. If nothing else, she's always a great design for clothing.
Of course, the new characters are also tempting. Like you pointed out, Marisa looks cool. It's like they saw Rhonda Rousey and said, "Could be beefier". Not sure how intimidating a dude called JP is going to be though, but it's good how we're getting more than just 4 new characters from the beginning.
