Really this just comes down to your own personal preference, and there are strong arguments for using them and avoiding them. If you’re someone who needs the keyboard to be almost silent, then membrane switches are probably the best choice for you. People who share a sleeping space or bedroom should consider membrane switches or anyone for whom too much noise is annoying or unwanted. If you’re someone who wants good performance and a more responsive feel however you will struggle with membrane switches and may prefer to use the alternative, mechanical switches. If a little bit of additional noise is acceptable, a quiet mechanical switch may be a good compromise in terms of quietness and performance. There are several excellent mechanical switches out there which you can use to get great performance without raising the noise levels too high, however for some even this smaller amount of noise can be annoying, and there is definitely a noticeable difference in sound level between a membrane and mechanical keyboard.
