The ANF have also done some work on “what rules” and I can recommend their blog: http://avonnapoleonicfellowship.blogspot.com.au/p/evaluating-rules.html
They are 1/72nd scale die-hards and I’ve participated in a couple of their big games using their adaption of Shako. I have been inspired enough to get my old Airfix 1/72nd scale units out and even to have a go at painting up some more. I have to say it is a reasonably priced alternative, particularly given the figures available today and if masses of figures are what you want.
This is an interesting question. My club, the NWS, recently did a survey of its members that indirectly covered this topic (the aim was to find out what people wanted to do for the Waterloo bicentenary). The results of the survey can be found here: http://napoleonicwargamingsociety.blogspot.com.au/2014/09/nws-survey-part-1-waterloo-1815-2015.html
The simple answer to the question which rules is probably any, but there was a slight preference for General de Brigade.
My bias is for Napoleon’s Battles (as I like big games where I am commanding a decent sized army, or at least a corps or two) and I am excited about a fourth edition about to be released soon. However I was in a minority of one :-). I also wouldn’t use those rules for 28mm.
All the best on your quest.
