Again, like your last thread kristoffer, it's a basis of opinion. There isn't an answer of which is the best one. Only you can decide which one you prefer

However I will post the differences between the two games so that you can decide. Or maybe get BOTH?
Choosing between the two partially depends on if you prefer classic RE style or new RE style. Then it depends on which story interests you more.
RE CODE: Veronica employs the classic RE style - static camera, the infamous (but beloved) 'tanky' controls, more puzzles, T-Virus zombies (the kind that eat your brains!). Set in 1998 (after the destruction of Raccoon City) it follows Claire Redfield who is searching for her brother Chris at an Umbrella facility. However she is captured, imprisoned on an island run by an unhinged aristocrat. She wakes up on the island to find it has suffered a biohazard, and needs to escape so that she can find her brother...

RE4 employs the newer RE style - over the shoulder camera, more action than puzzles, Las Plagas zombies ('Ganados' - intelligent, use weapons). It follows Leon in 2004, who has been employed by the government as a special agent. His assignment requires him to go to rural Spain to investigate the kidnapping of the US President's daughter, Ashley Graham. What he finds there is a new kind of evil compared to what he found in Raccoon City all those years ago...

Both games have been very highly regarded, and RE4 especially as it is often on 'best games ever' lists.
IMO I prefer CVX to RE4 but that's because I grew up with the older RE games. I love its story, the characters (apart from STEEEEEEEVE), the villains more than RE4's and it has my favourite soundtrack in the RE serious. But I love RE4 too, they're both amazing games, and both worth checking out
Whats wrong with the controls?
Not entirely sure why wesker_awesome is irritated with the controls, as every single RE game (RE5 aside) has employed R1 aim, X to shoot controls?
