I myself am an OTAS regular but usually stop after the Venti because I can purchase the next top level reward and use it to make much more profits than I would working to get the free one.
I've also worked for Plutarch & Johnferco, as both will eventually give up the keys to a Heavy Centaur P.
I think the Dukes will give a Medusa P ... but I've never worked for them.
PTNI will give a Kite Vanguard .... it's only an M4, but more like an M4+++.
Terracorp gives the Nova P at mid range reward, and a version of the Eclipse for the top spot. I stopped after the Nova P ... only needed a player ship, not an AI one.
I've never worked for Atraeus ... their top reward is a copy of a free ship you can just claim, and all are Boron vessels, for which my character does not breathe water, so does not fly. When I do decide to start as Boron, I'll play as those are the only ships my character can fly or have.
Here's a link to a thread with all of the rewards spelled out.

) and getting close to getting the Venti ( 
whoop whoop) but what else can you get from say completing the Duke Buccaneers missions or any of the others Corporations, have they been done? is there a list?, by doing different starts saying the unholy traitor would you get different gifts from the Strong Arms Corporation ?
