I have heard people like that one, and I have read roughly what it's about, but I'm saving that one for my next playthrough.

I think which one suits best depends a lot on both how you played your V and how you felt about Johnny.

For me, V and Johnny became like best friends, and so The Sun ended up feeling mostly like a letdown and a nobody wins scenario, and it felt almost out of character for V, too.

Temperance felt perfect for the story as I had experienced it, and it was also really cool to see the final dialogues inside Mikoshi from both the perspective of playing as Johnny and playing as V. Highly recommended.

SPOILERS When playing as Johnny (the first time), I actually thought V would interrupt a fourth time on the bridge heading towards the light and forcibly kick Johnny back into his body and make the choice for him. At least that's where it felt like the dialogues were going. I think that would have been a cool moment, if your relationship with Johnny is high enough.
