Oh, that's technically true, but (and I have el zilcho experience with SFB except owning one pewter minature of the Ent-A) one can, and definitely you of all people, easily extrapolate TOSish or SFBish stats to numbers that would more than roughly model what we've seen in the Kirk-Spock-McCoy movies.
I'd rather think that it's the TNG era that'd be hard as heck to model using SFB stats. Their weapons are just too powerful.
OT: TOS (the Feds, natch) evokes in my imagination America between and up to WWII/Korean War era- more powerful than it realizes but still a but unsteady and unsure about itself in the face of yet unknown dangers. From Janeway's words in Voyager- how big space must have seemed then to Kirk, Sulu, etc.
TMP gets compared in my eye to Vietnam War/Cold War era America, a power challenged, but one which is now a bit more aware of its muscle, though still quite wary of the powerful rivals it has.
TNG? Heck, that in my mind is like post-Soviet Union America- haughty because it has reason to be, feared because it has reason to be, envied because it has reason to be, poised on the verge of something critical, something grand, something noble, yet the stakes are quite high because it represents something golden for all men and the possibility of either abject failure through blindness to dangers due its elevated pride or just pissing it all away due to affluence induced apathy or callousness is all too real... not that its enemies (Borg, Q [maybe], Roms, Klinks, whomever the heck else... and the real world analogues for the U.S.) are such a noble assemblage.
The SFB ruleset, or so it seems to me from the uninitated's distance, is characterized throughout by checks and balances. How can this apply to a pre-eminent power, such as TNG or post TNG Federation's Starfleet? Boy, they can even whip the Borg, with a bit of sneakiness.
Actually, this gives me an idea for a post TNG era show- and I hope someone with the right connections steals this idea and puts it on the airwaves. I'd love to see a new ST series based on Starfleet having to help stave off some moderate to weak external powers, but some unsettling internal dissonances, such as the Ludditish Vulcan movement to withdraw from the UFP, heated provinicial disputes leading to skirmishes between neighboring Federation systems, and difficulties in incorporating new frontiers into the Federation, non-humanoid Federation races having real anti-humanoid grievances. Seeing creative solutions from a crack crew on the best starship of Starfleet (the Big E, of course) to such things would be great.
