I have way too many favorites to list any one band over all the others.
That being said…
If I could only listen to one heavy metal band for the rest of my life, in some sort of bizarre heavy metal desert island situation, Motörhead would be it.
I really love death metal and all the classic Earache bands, but I wouldn’t want to listen to that stuff allthetime
Ditto for black metal. Real black metal fans only listen to it in the winter anyway (adjusts monocle after setting down bone china tea cup).
Black Sabbath with Ozzy was phenomenal, but they only had, what, eight albums together? Not enough to spend all eternity listening to.
Same goes for Metallica. Only four albums and an EP! Not enough material.
Slayer does have a large discography, but each and every album is 100% IN YOUR FACE ALL THE TIME, and like death metal, might get very tiring after awhile.
Motörhead has 21 studio albums, four major line-ups, and songs ranging from IN YOUR FACE HEAVY METAL to relatively radio-friendly classic rock ‘n’ roll (I won’t mention the ballads). Lemmy himself has stated countless times that Motörhead is a rock ‘n’ roll band, and not heavy metal (sure thing Lemmy, not at all heavy metal, gotcha).
Lyrics are generally about life, love, rocking, rolling, riding motorcycles, and playing cards. Very broad themes which would get much less tiresome than hearing about SATAN!!! every other song.
Plus there are cameos by Ozzy, Wendy O. Williams, and Michael Palin, just to shake things up a little.
Finally, Lemmy was previously bassist in The Mighty Hawkwind, so he gets extra credit for that.
