Code Geass. I prefer it to Death Note because of how the story plays out. Death Note also just was a bit boring after এল-মৃত্যু পত্র died and I didn't like how they acted afterwards. Mello and Near were okay and all but it just seems that Light wasn't all into besting them. He just wanted them dead so they didn't get in his way. Also,the animation,the plot and the main characters from Code Geass are better. There's a bit আরো humor,less annoying characters and সামগ্রিক better plot structures.
If I had to choose Death Note. I like how it proved a series doesn't need a bunch of action অথবা blood for a series to be really exciting and keep আপনি on the edge of your seat. I just loves the way Death Note bent my mind and really made me think. Though, I প্রণয় Code Geass as well~
Plot wise, I prefer Death Note because I just প্রণয় how mind bending it got at times. It was an সামগ্রিক joy to watch for me and it still remains my পছন্দ anime.
Character wise, I have to say I prefer Code Geass's. It's not that I dislike Death Note's characters, I really do প্রণয় most of them, it's just that the Code Geass set of characters were আরো interesting to me.
