I was wondering the same thing for a while but nobody can really answer that man. There's no such thing as "the best" cfg mod menu. There may be better menus that others, but most menus really have the same options. It's all about preference and opinion.

Personally, I iWerc's v5 menu is really good. Also you can go to youtube and search "Top 5 cfg mod menus" or something along the lines to get some ideas and have a range of menus to choose from that maybe you haven't seen before, that's what I do.
