I would definitly say both. Man he kicks a$$ on Song Remains The Same video, playn´ some really cool stuff and fast too. I think during that time period his technique was absolutly world class and I don´t think that there were many famous guitar players that could beat him.

When it comes to songwritning, o my god. Words aren´t enough. Jimi, Sabbath, Purple and Zeppelin were the most important bands in rock music and I always liked Zepp most.

Comunication Breakdown, Dazed And Confused (song remains the same verision), Wholla Lota Love, Heartbreaker (shred), Thank You, Stairway To Heaven, Black Dog, Song Remains The Same, Rain Song, Achilles Last Stand, Kashmir, Imigrant Song.... i could go on and on. All this songs are just perfect and none of these "big 4" had such a huge musical talent as Page/Plant had.
