I would like to ask why Staraptor is in UUBL?
It doesn't even at least have a dex entry for singles and is nowhere to be seen in any OU viability ranking.
Is it actually broken in UU? I mean M-Aerodactyl and guts swellow can be used in UU and they're not broken at all. S
Adding to what Dreadfury said:
Staraptor in OU is incredibly niche - limited to what are known as "bird spam" cores that are hyper offense builds. It can be used in OU to some limited degree, but you would have to ask yourself why to use Staraptor over many OU Pokemon outside of "I like it" (which isn't usually a good justification for being optimal nor viable). STAB Double Edge and STAB Brave Bird with Reckless is very potent, as STAB Double Edge can wipe out some of Mega Pinsir's problematic Pokemon such as Rotom-W and wear down Zapdos while giving more opportunities to sweep.
As far as the UU decision, I would highly suggest the question is a bit more suited for UU; however, it was a Pokemon given a second chance and then banned. I do not have the ban post on hand, but a lot of it is due to Choice Band Reckless just having insane damage output.
For your comparisons - Mega Aerodactyl is strong, but it's rather underwhelming because the majority of its moves barely break past 100 BP (even with Tough Claws at times) and the reliance of Aerial Ace or Wing Attack for Flying-type STAB can be very underwhelming. Being reliant on a Mega Evolution has an opportunity cost in the various tiers - very high in OU since Mega Alakazam and Mega Lati@s are very potent, and UU having other viable Megas such as Mega Aggron, Mega Beedrill, and Mega Altaria (note - I don't give a damn about their rankings, I'm just pointing out that there are Mega opportunity costs). Swellow is a different story - while Guts Swellow was sometimes a thing in DPP (albeit a terrible thing in OU IMO), Guts Swellow has the major problem of wearing down very quickly and lacking a lot of power prior to and even after Guts is activated. Specs is arguably better as well since Scrappy STAB Boomburst can actually do some major damage to teams that aren't loaded with Normal-type resists or special sponges like Blissey.
Using Mew (fuck EVs), here's a relative example of power difference between the three Pokemon:
252 Atk Choice Band Reckless Staraptor Brave Bird vs. 240 HP / 156 Def Mew: 286-337 (71.3 - 84%) -- guaranteed 2HKO after Leftovers recovery
252 Atk Aerodactyl-Mega Stone Edge vs. 240 HP / 156 Def Mew: 144-171 (35.9 - 42.6%) -- 94% chance to 3HKO after Leftovers recovery
252 Atk Guts Swellow Brave Bird vs. 240 HP / 156 Def Mew: 189-223 (47.1 - 55.6%) -- 19.1% chance to 2HKO after Leftovers recovery
And to show a difference with Scarf Staraptor:
252 Atk Reckless Staraptor Brave Bird vs. 240 HP / 156 Def Mew: 192-226 (47.8 - 56.3%) -- 28.1% chance to 2HKO after Leftovers recovery
Finally in regards to its analysis - usually, if a Pokemon is extremely fringe or not considered very viable within a tier, it usually will lack an analysis regardless if it is UUBL. This would also explain why Pokemon like Salamence are often missing an analysis.
tl;dr version - Staraptor is simply way too strong by UU's standards (per the previous votes) and its niche has not been called upon as of late within OU (but anything can change with that as meta trends vary significantly and OLT is a season that has a lot of HO spammed).
