Tampax Free Sample

What’s the difference between Playtex Sport and Playtex Gentle Glides?

Ok, so I’ve been using Tampax Pearl, (reg.) but I’ve noticed it’s started to leak without being very full…
Anyway, I got free samples of Playtex Gentle Glides and Playtex Sport and I really like them, no leaks and what not. (still reg.)
But is there any real difference between the two? I mean, beside the applicator and name?
Because it looks like Gentle Glides are cheaper here, but do the Sport ones really work better?

I’ve used both. I didn’t notice a significant difference. They both offered very good protection. Right now I buy the Gentle Glides. No complaints.
