I am doing the same comparrison and am leaning strongly toward LED myself. It just seems that the long term cost of LED's is hard to beat. Even if a few burn out early and need to be replaced after about 1 year they have paid for the increased cost and have 5-10 years left of life span. even at 400 per year replacement cost for bulbs that sholde be 3000 in savings plus electricity.
As for SPS liking them the key seems to be using enough LED's and dimmable ballasts so you can fine tune the color.
