I will always like Sonic 1 over SMW. There are tons of people if you search around that like Mario 3 over SMW. I'm not one of them but there are plenty out there. Sonic 1 that year was a game fresh and new. I really enjoyed it and still do.
I hear what you are saying: Sonic 1 really was fresh, new and exciting when it came out. I remember the feeling—it seemed as if we jumped into the future...it's how I felt playing the NEO AES at JC Penny for hours every day one summer...this is the future of home gaming!
As for SMB 3 vs SMW...I love both, but SMW really starts off in a plodding, anticlimatic manner, especially in context of "next generation" marketing for consoles—SMW's ho-hum initial impression is *not* what (I) we were expecting our first few moments to be like with a brand new installment on a brand new console. I remember thinking "OK" (I felt the same way about Gradius III). I actually love Gradius III (I know I am in the minority), slowdown and all. It's just not what I was expecting after BLAZING LAZERS was my first impression for TG-16, for example.
However, what's funny is that, over the years, Sonic games (the mechanics) have not retained that magic for me anymore (too jaded)...
Yet, I go back to Mario games all the time. I love slow, plodding Gradius III.
Sonic?
Occasionally.
Sorry Sonic

And, to settle things: I don't think Sonic CD is the best...it's not better than the first two installments... I like Sonic CD, but maybe my expectations were unrealistic? Because I wanted Sonic CD to somehow capture the magic of first two Sonics... and then MOAR.
So: I know I may not be judging Sonic CD objectively, but it will never wear a GOLD or SILVER medal.

BACK ON TOPIC: I love SMW, but I couldn't help feeling, initially, that since SMB3 was so much damn fun to play, and so immediate, frenetic, energized... SMW had to prove itself. There was no automatic passes. SMW had to win me over and prove that it, truly, was a great game. It eventually did. But I feel that SMB3's "instant classic" status was achieved almost immediately, whereas SMW took some time before I was convinced it was a masterpiece.
