Straight tip – It will help you capture that stray hair (e.g., around the chin area) and it definitely lends itself to a search and pluck technique.  It’s also terrific for plucking several hairs at once the larger surface of this tip does the trick.
Slanted tip  – You can get quite close to your skin and have no trouble pulling the hair out to its root. Compared to a tip point, with a slant tip you get more speed with just a little less accuracy.
Rounded tip – This is a kinder, gentler tweezer. This tweezer will grasp the hair and hold it until you pull it out.
