On Through the Night was a great debut album from these guys, and the follow-up High 'N' Dry was no slouch, either, with cuts like Let It Go, Another Hit and Run, the title track, Lady Strange and one of the least wimpy ballads out there in Bringin' On the Heartbreak.
Pyromania was a great album as well. I was in 10th grade when that album came out. The three hits were great, but like the other two albums, the deep cuts were just as strong.
Hysteria was an album I did and still do like, but it had a bit too much polish on it. I understand that the band had a great deal of time with Rick Allen recovering and getting acclimated to his new style of drumming and kit, still, the album was chock full of hits...I could go the rest of my life without hearing Pour Some Sugar ever again.
I agree with David, Retroactive had some great B-sides on it, and is a good choice if you're looking to collect everything available from the Steve Clark era.
I must admit, I really haven't paid much attention to them since Steve's passing. I gave Adrenalize a few spins when it first came out, but haven't owned or listened to it since.
Hard to believe he's been gone twenty years this past January.
As an aside, Tesla paid tribute to Steve Clark on the track 'Song & Emotion' from the album Psychotic Supper.
Speaking of Tributes, this was a great one the band put together in memory of their friend:

Whenever I put on Blizzard or Diary, what a wonderful, delicate furious beast.... I MISS you, man!
