Favourite time mode and why?

What is your favourite time mode? How much time you like best to have with your opponent? If you ask me, my favourite is blitz 5 minutes. I like fast games, like 5 or less minutes, but I choose 5 as favourite because it is fast, while not so fast you can't think properly. I like lightning (1 minute) games as well, but it knows to be too fast, so you can lose 1 move before mate, which can be apsurd, or win while your opponent is very close to victory. What do you think about it?

i like my standard games best 15-10 and 30 min, i like my blitz and bullet as well, but i think to play properly, you need a bit of time, still cant get anyone to play a 60 min game tho
