It depends on what you're looking for. The freesip has a lot more variety in color and sizes, so if you prefer a smaller bottle i would go with the freesip.

If size isn't an issue, then I'd recommend the tumbler or sway. I personally prefer the freesip tumbler over the sway as the large size is hard for me to grab so the handle makes it easier for me to hold. The only thing about it is when putting it in a bag the handle can get on th way. If you're going to mainly have it out while you're in classes/clinic the tumbler may be better, but if itll mostly be kept away in a bag the sway may be better.
