I've always thought the molten-salt designs were particularly elegant.
They can be configured as breeders, with the ability to burn Thorium
(Th-U233 cycle) as well as U / Pu, and even heavier actinides from LWR
waste. The coolant loop is low-pressure and chemically inert, hence
safer than water on both counts.
I could be a tad biased from having read Weinberg's book, though.
