Depends on your criteria, the Contigo ones and Stanley ones are great because they offer "spill proof " protection With screw on lids and closeable sip. I prefer my rambler over all others for everyday use, travel etc. I prefer no handles as they fit in most cupholders better. It's not spill proof but certainly resistant, and very easy it is to clean. Many of them have small tops and hands don't fit for a quick wash and rinse, the rambler styles don't have that problem.
