What is the best doors album in your opinion?

Strange Days.

PS: First album to use the first of electric mics.

The Doors and Strange Days tied for first. I only wish Light My Fire had been recorded better.

Of course there is no "best" here, just favorites. Mine are, Soft Parade and Waiting for the Sun.
Drove from Minnesota to Miami in 1968 with one 8 track tape, The Doors. 32 hours each way, don't know how many times I listened to that tape. Still like the album though.
BTW: Saw the Doors twice. 8^)

“Morrison Hotel.” IMO, a masterpiece from start to finish. It’s hard to argue against “The Doors” for musical and cultural significance, but for me, MH is where it’s at in the Doors’ catalog. That said, I like all the albums—just some more than others.

My favourite is a compilation double CD titled Legacy: The Absolute Best of The Doors which came out in 2003. My previous favourite was The Best of The Doors from 1985 which I gave to my brother to enjoy. The newer compilation has 34 tracks which are all HDCD encoded and the older double CD has 19 tracks with inferior sound quality. Although my wife and I really enjoyed the older CD on our honeymoon while driving through the Grand Canyon National Park. Great memories with The Doors, my wife and beautiful scenery.
