Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

• ChaCha and Salsa20 are 256-bit stream ciphers which can output $$2^{64} \times 512$$ bits of data per key.
• AES in CTR mode is secure, but becomes distinguishable after generating about $$2^{64} \times 128$$ bits.
