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

For my littel horror of a two year old he can open the take and toss ones by either using his teeth or throwing it on the gorund and the lids pops off and we have water everywhere. So these definitly don't work for us, although i do have some for DD to try

I have a tommee tippee one for Miss M and also a pigeon one that does three stages of development.

But usually I just use one of her smaller bottles cos I'm lazy and its just there.. lol

DS uses the toss ones....

ETA - I have a Kala one and it is BRILLIANT - no spills.

We have a Tommy Tippee one for Bubbablue. It seems to be really good.
I don't remember what type we had for DS1, which sucks cause it was reallyyyyyy good.
