One of the most important considerations to make when looking for the best pick for you is the shape, as this is going to affect how to physically connect with the thing. Choosing a shape that feels comfortable for you to hold and play with is important. It depends how you hold your pick, but if you like lots of plastic between your thumb and finger, then a pick with more body to it could work better.
The point is also important. Many players find that a finer point leads to greater accuracy, particularly when it comes to picking out individual strings. Something a little more rounded, like the standard pick shape tends to be a fairly good all-rounder, as the point allows for picking out individual strings, but it’s wide enough to make strumming easy for most playing styles too. There are even picks that have different shaped sides, each one lending themselves to different playing situations.
