No personal experience with any/either of your options.
So, this might seem silly, but if you fire them both up, and put the engines under some acceleration stress, which one runs quieter? At idle, which one? At slower neighborhood speeds? Freeway cruising?
I'd choose the quieter one of the two/group.
Just sayin'...
