I can't help with the Dacor but I may can shed some light on the Ranger.
I own one and have quite a few dives on it. While it's a good BC, I do find it a little overkill for most of the diving I do. I don't need 45lbs of lift and it's extra heavy material is just not necessary. It's rare that someone can actually wear out a BC. If I needed a lot more weight (and the lift to go with it) then it would be fine. While I still own it and do dive it on occasion I perfer the similar but much lighter Scout. For comparison, the Ranger has 45 lbs lift and weights 8 lbs dry, the Scout has 35lbs of lift and weighs 4lbs (actually a little less but I have added a Ranger cumberbun). Since I rarely use more than 10 lbs of weight and use only AL-80 tanks, the 35lbs of lift is still more than I need. The cost is also about half. If I were buying again and could buy only one BC, I think I would opt for the Escape, mainly due to the very minimal intergrated weight system that the Scout has. On the other extreme, if I were going to be diving doubles I would go to the BP/wings. I personally find them somewhat uncomfortable above water but they do a much better job with doubles than most any other BC.
Hope that helps.
I have to agree with gjw, next time, a better title will help you get more responces.
