The best sippy cups?

Kelcie • I`m Kelcie! 20 year old mommy to an 8 month old girl.
My daughter is 9 months old and she has 6 teeth now so when she's done drinking out of her Learners cup she will chew the nipple and she can't drink out of it anymore. My mother-in-law suggested a sippy cup. What do you guys think? I know they have a lot of different bottles and sippy cups, any recommendations? Please also list where to get them from, thanks!!
