I just don't think being a good revenge killer alone is enough to justify having a set, especially when you consider it loses to a lot of good of Pokemon. It doesn't revenge kill every sweeper in the metagame; it really only gets Terrakion, Hydreigon, Lucario, Starmie*, Latios*, Alakazam, Kyurem and Mamoswine. (you need to gamble if you want to revenge kill Starmie or Latios and you only get one chance, if your opponent sees through Sucker Punch, you're dead in the water)*
I can admit that a well played TechniTop is probably on par / better at straight up revenge killing than Breloom/Scizor, but it has nothing else to offer. Breloom can Spore / Sweep & Scizor is... well Scizor. What else can it do outside of revenge killing besides being able to tank a Close Combat from Scarf Terrakion?
The part I bolded is actually inaccruate. You don't need to be super effective to revenge kill things. That is the whole point of Fake Out. Fake Out + Mach Punch muscles through many sweepers. Here are some combo calculations on the pokemon you didn't mention:
Fake Out + Mach Punch
Jolteon - 105% minimum damage
Infernape - 85-100%
Alakazam - 97-100%
Haxorus - 67-80%
Breloom - 85-100%
Garchomp - 52-64%
Venusaur - 50-61%
Keldeo - 62-75%
Now, you cannot tell me the extra damage from Fake Out isn't huge when you are facing a sweep. The perk of using Technitop as a revenge killer is that is the majority of sweepers in OU making the cut (save the obvious Volcarona, Dragonite, Thundurus-T) and he doesn't need a choice item to do it.
For what it's worth, Sucker Punch is kind of meh. It is too predictable and you are better off using Pursuit for those targets (especially if Fake Out takes them low on health). Pursuit and Stone Edge where the only things I've bothered using in the 4th slot. Stone Edge at least keeps Dragonite and Volcarona from getting too greedy.
