To answer your question about different key switch types, I would highly recommend taking your next move carefully lol. Once you feel mechanical switches under your fingers, you can't ever really go back and enjoy membrane keyboards . For somebody that types all day, I would actually recommend a switch that allows you to feel the tactile point of actuation such as Blues. It's much more satisfying in my opinion and they generally are regarded as the best to type with. Red switches don't have a tactile feel for the actuation point and so they just slide until they bottom out. A more silent version of the Blue switch would be Brown switches and are sort of a happy medium between the two as they aren't super clicky clacky, but still have that tactile feel when depressing the key. However, regardless of the switch type, if you are plunging the keys hard enough to bottom out with every stroke, no mechanical keyboard will be truly silent. When at home I use Blue switches as the sound makes my heart happy and the feel is the best out of any switch type I own. I personally use Brown switches when in an office environment and I have never gotten any complaints from co-workers. I know that this is a lot of words to not really answer your question, but I hope to give you some things to think about that videos sometimes don't convey about different keyboard types since mechanical keyboards aren't inexpensive. Hope this helps!
