Without wishing to be rude, it's a bit of a silly question. One steel frame is nothing like another steel frame, one aluminium frame is nothing like another aluminium frame. A doubled-butted steel frame is better than a plain-gauge aluminium frame. A doubled-butted aluminium frame is better than a plain-gauge steel frame. The quality is more important than the material.
If it helps, I have the June 1995 MBUK here. In a test of three aluminium bikes, the Orange E3 was reckoned easily the best, the Cannondale M900 not. The M900 weighed 3.8lbs and was described as a 'good, solid frame'. The E3 weighed 3.4lbs and was described as 'superb'.
The E3 was made of generic 7005. I have just built up an Orange E4, which is made of Easton Elite and weighs about the same as the E3. I find it rides pretty similarly to high-end steel frames, maybe more solid feeling, but not uncomfortable at all. The only aluminium hardtail I had ridden before was a 1999 Stumpjumper M2 that I bought and set up for a friend. He is very pleased with it, but I thought it was terrible - heavy and dead compared to my lighter steel bikes.
