I don't own a 1 series film camera, so can't comment on those. But I own a lot of others. The Elan 7e and the Eos 3 are my favourites. I've had my 7e for over 10 years and it has been a great camera. Last year, I purchased an Eos 3. Overall, I'd agree that it is better than the 7e. Since buying the 3, the 7e has lived on the shelf.
For what its worth, my favourite film camera is a Mamiya 6, which is my no 1 camera. Also, despite some drawbacks, some of my favourite photos have been taken with a Mamiya RB67 Pro S (WOW - Didn't know there were so many other Mamiya people on this forum!). And I think this is where it gets interesting. Why would you want to shoot 35mm film given the superiority of digital over that format? Plus you've also got to consider the hassle of developing it. And the cost of buying film. If you shoot Large Format (or if you're not hard core enough, medium format like me), at least you can argue that you're on a similar quality level. And many large format cameras offer movements / adjustments that can give your photos a very unique look. The benefit of medium format is that you have very large negatives to play use. This makes developing and printing at home a lot easier. And serioulsy, given the prices right now, I'd be looking at a Hasselblad. And not that its that relevant, but for some reason, girls find guys with Hasselblad's very sexy. (Look at the advertising for a lot of premium brands and you'll be surprised how often these cameras appear).
