I'm going to have to say Ubisoft right now.
On the PC front, EA seems to put more effort into their ports, and if we have to use Origin/Uplay, Origin actually functions every time I use it and has a refund policy.
EA got rid of the Online pass, and will allow owners of used games to download online pass shit now without paying (the original Alice for Madness Returns).
Whenever a busted as fuck game has released on the EA front patches start coming out quickly and development on DLC will halt in order to fix it (BF4 vs Unity). Though to be frank nothing that has shipped as gold should be busted as fuck.
EA gave Bioware some actual time to work on Inquisition, and as far as I can tell Inquisition hasn't launched with tons of very story important characters and quests as DLC. Ubisoft would like you to integrate with smartphone apps and there is a 100% chance of a request to pre-order $30 worth of DLC even if the game itself isn't finished (not to say EA has walked away from the Season pass, they just seem to understand the gravity of asking for a $30 DLC preorder and don't pull that card for every single fucking game).
A negative for EA, but they totally fucked the Dead Space franchise. Though Ubisoft is so obsessed with having an entry multiple times a year to the point that all franchises of theirs outside of Rayman are guaranteed to be fucked.
EA has a way better PR team. They don't exactly say brilliant pro-consumer shit, but they seem to know when to put your foot in your mouth. Ubisoft takes every opportunity to dig the fuck out of their graves, incessantly insulting the customer's intelligence and dishing out bizarre justifications for the problems of games.
Both of them represent a lot of the problems with modern AAA development, but I personally see EA trying to take positive steps as they still act as a business and maximize profits in the process. Ubisoft has only gotten worse and worse since like AC2, and I'm still pissed that Beyond Good and Evil 2 was teased a lot for awhile there and then we heard nothing.
