I don't have to think about switch out when I go outside with transition lenses. But sometimes they don't get as dark as fast as you see in the advertisement definitely. So which one do you prefer? Sunglasses or transition glasses?

You should not define a pair of eyeglass good or bad by how buch sunlight it block but how much harmful rays it block.

personally, you can try to wear any kinds of sunglasses as you like. The single sunglasses are just for protecting eyes from dangerous rays, while the trasition ones is much more convineint that you don't need to take off them where is darker. Here I suggest you to find another sunglasses named prescription sunglasses which designed for high myopia suffers to get ease from wearing two glasses. Maybe that will be the best for you.
