Thank you for your question! The model 470-DST has a solid handle and the 472-DST has a loop handle. "WE" models are Water Efficient and have a lower flow rate than non-WE models (currently 1.5 GPM and 1.8 GPM). The "AR" suffix refers to the finish color Arctic Stainless. Models without a finish suffix (AR, BL, WH) are Chrome.
Please see the Technical Specifications for more information:
Best regards, Jon
