Had a quick look over Marshall - not sure at first glance whether much needs added or changed. Seems very nicely covered.
May I suggest you take a peek at something else tho - which may be of interest. Guy on THR not so long ago put together a chart type deal with a lot of small guns and it does give some quite handy representative comparisons. It went thru several incarnations but IIRC the one I show is pretty much his latest.
It is on my R9 FAQ site and this is the relevent page. You'll see a link to a PDF file - the pic on that page is only for starters, as definition not brilliant.
