The tieflings are shortchanged vs the aasimars again... the ARG misses the worthwhile bit of the tiefling standalone product (like possible different ability modifiers that make the fiendish sorcery worthwhile at last).
Aasimar gain racial feats for true flight and metallic skin while tieflings can at best gain small vestigal wings as a racial trait...
The Merfolk have 3 +2 traits, natural armor and trip immunity for the penalty of having 15ft landspeed (with an optional racial trait). Higher level characters can ignore the weakness entirely thanks to a CL/hours spell that changes their fin to legs.
An interesting book, but beware of powercreep and non-balanced options.
