Rubber Soul is not the best Beatles album but let me tell you why it's my favorite.
it has the very first beatles song that i loved (norwegian wood)
it has the best ringo song (what goes on)
it has the first great george song (if i needed someone)
it has a great wink wink sex joke song (drive my car)
it doesn't have a trash ass wtf paul genre song. the closest thing is michelle, and michelle is effing great
it has 14 songs and only one skip (think for yourself)
it has the most lol cringe john song (run for your life) but damn if it isn't catchy af
it has one of the very best john songs (in my life)
imo this is the last album that fully belongs to john. Norwegian Wood, In My Life, Nowhere Man, Girl, Wait. none of Paul's top 5 (10?) songs are on Rubber Soul, but he has several good ones (You Won't See Me, Drive My Car, Michelle, I'm Looking Through You)
along with Help! (also in 1965) this is when they started doing more badass music stuff (more prominent bass, more intricate guitar from george, sitar on norwegian wood, the cool drone thing on you won't see me, etc), but before going fully nuts in 1967 and 1968. it's a very transitional album which is kind of cool.
