I's stick with the Sugino in 46/36/24. I like to use TA rings so I buy the crank without the rings. If you want to stop dings on the chainstay use a chainstay protector.

I use a 46/36/24 and 12/34 combo and I've never had the chain come off. You can limit that possibility by good FD adjustment and keeping cross chaining to a minimum.
