What am I looking for in a sippy cup? Recommendations?

[feeb]

we have a Happy Baby one and its great.

Has rubbery top that they need to squeeze in mouth to open small valve, does not leak and DS loves chewing on top.

It has 2 handles and it is slanted so they dont need to tip as far to get a drink.

Also have take and toss but they leak when chucked on floor or tipped upside down.
