Selena Gomez
- sold more singles
- has had more of an impact
- is more known worldwide
- Wizards of Waverly Place was more critically and commercially received than Lizzie McGuire
- acting career has had more longevity and success
Hillary Duff
- sold more albums
- I've only heard one or two songs from her (With Love and Wake Up)
- doesn't have a song that's platinum whereas Selena has multiple (nearly all except one)
- her acting career isn't very successful currently
I like Hillary I'm just sharing my opinion so please don't hate. We can talk this out without conflict.
