Technic: 7 letters.
Better Than Technic: 17 letters, 3 spaces.
Somehow, I think it would be more beneficial to compare to the 1.2.5 dev build at the moment, since it's a closer comparison. Does BTT have a dev build cycle of some sort we can be even more even with?
Are we counting Buildcraft and Redpower the same number of times on both sides? I don't really think it's worth counting every single subpiece of a mod as separate mods, even if that skewers those numbers further one way or the other.
Also, how "big" are these mods? A mod that just adds five new flowers is still a mod, but Technic probably wouldn't bother with something that minor unless they were some sort of laser-shooting death flowers or something. Oh, or had creeper faces. Ultimately, tricky to compare a basic number like that, especially if both packs have the same "big mods" and one adds in a bunch of smaller, useless or boring mods. (Which in turn is a subjective thing as well.)
Same seed/stuff going on nearby? Do both mod packs have the same mods that can cause a lot of FPS dropping installed, or BTT dropping some of the laggier mods?
+1 Hellen Keller point for not reading stickies.
So, the only important parts in your summary above involves the number of mods and FPS, which means nothing else you stated was important enough to include in your summary.
Personally, I think a more useful comparison is the "feature list" table you see in a lot of product comparisons on corporate websites. I would write a four column table with the name of the mod, the version for each mod pack (or a nice big red Not Included) and a final column for a description of what that mod does, in a one sentence summary. This would allow a person new to these mods the ability to quickly figure out which set of mods better suits their playstyle while at the same time helping everyone discover new mods they may not have heard of AND helping your original target audience of people find which they like better.
