I have used both. In my experience both can be made to work very well. Contact lenses probably have the edge in sharpness but not by a large amount. In sunny weather the need for sunglasses negates the advantage of not wearing spectacles anyway.
The easiest way to try contacts is to use daily disposable lenses. These are the very thin foil type lenses. Putting them in just takes some practice. It's not that difficult. Any optician can show how to do it correctly. Even disposables are available with a correction for astigmatism. They are a bit harder to put in as they have direction markers on the lens. They work very well but are fairly expensive when used daily.
