Which of these amps is the best?

The only way to decide is to try out each of these amps actually using the guitar that you are also interested in. People may say this one or that one is best, but ultimately deciding on the tone that suits you best can only be discerned by your ear. Good luck in finding the sound that you are looking for--you will surely know it when you hear it, and you will be glad that you took the time and made the effort to find it.
