I just went through the same decision a month ago. I was originally going to get the Deluxe 28, but ended up really liking the Platinum 24 and ended up getting that instead. I couldn't have been happier with this decision.
For one, the built-in headlight looks better on the Platinum than having the external headlight mounted on a handlebar like on the Deluxe. (Although since the unit on the Deluxe is mounted up higher, it might perform a bit better. There is a pretty big shadow on the ground directly in front of the bucket on the Platinum.)
The quick-turn locking lever for chute rotation on the Platinum is much nicer than the "ice drill" manual crank on the Deluxe. I don't have any experience with the "ice drill" chute, but on previous machines I've owned, I've always experienced the chute rotating on its own due to vibration or the snow. The quick-turn chute on the Platinum locks into place so it will not creep around.
The handwarmers are awesome. (They are available on the Deluxe for $70 though and anyone buying a Deluxe should add them) I was clearing snow this past weekend in the single digits/low teens, and my hands never got the slightest bit cold.
But the biggest feature for me was the traction control. I experimented with one at my dealer as I was trying to decide, and this is what sealed the deal for me. I don't understand some of the people on this site that say the ATC models are too hard to control and they'd rather have a unit with the manually unlocking wheels. I've found that the ATC is completely seamless in its operation. The slightest bit of push by me on either handlebar will make the snowblower turn. There is no need to stop in order to latch or unlatch the wheel.
I would have liked a 26" wide bucket, but I just look at it that if it takes 1 or 2 more passes to clear my driveway, it's just a little more time I get to spend using my new toy.
