My site is about improving stability and creating a clean setup, not just boosting FPS. What do you mean by success? OOO+MMM simply has less load order issues to be concerned with. Getting two overhauls to work together is not nearly as difficult, especially as those two do not overlap as much as a full FCOM setup. I used to consider MMM simply a huge creature and diversity adding mods, but it is more overhaul-ish now. However, it is really up to the user to make it that way since MMM is so modular. OOO full is more all-in-one. There are not too many options. It is more of an "as is" overhaul, so its problems are more contained. Overall, those two mods together is a less complicated mess, not to mention MMM's new readme is fantastic. Almost of of the "shoulds" and "should nots" are explicitly found in the ReadMe for the MMM+OOO setup. That is much harder to do with FCOM because it is also modular and covers a lot more ground with more mods that overlap with each other (and used different systems.) Dev_akm could not predict every possible configuration. That is part of the reason why it would be preferable for a user fairly comfortable with mods, especially overhauls, to attempt its installation. That user should have more insight with which to figure out what should be loaded give a certain choice of configuration.
Success means a fairly stable game (a CTD maybe once in a 2 hour game which I achieved by using crash prevention and 4gb patch, down from 1 CTD within every hour). All my FCOM setups only focused on the 4 major mods, Frans, OOO, Warcry, and MMM. I stayed away from the other addins as they were more cosmetic, so never had an issue with FCOM load order. For me Oblivion is about puzzles, quests, sneaking and working for loot, gathering trophies, and of course the fantastic visuals. So mods outside of FCOM are about making the game more immersive and realistic.
What your guide and some others are good for is steps to REALLY put in a good number of mods which can make the game stable and SPECTACULAR, with yours being very well suited for those who don't want to know too much about what is under the hood, just give them the keys and let them drive.
