what is the best time control

what is the best time control 5 + 0 blitz 10 + 0 rapid 30 + 0 classical 1 + 0 bullet 15 + 0 ultrabullet 1 day correspondence

There is no best time control, some players may prefer quick games (bullet and blitz) and others may prefer classical and rapid. If you want to see how good you are at chess however, you should either play classical or rapid.

I think 30+0 is the best time control.We can practice If we play 30+0.

What do you even mean by “best”?

The best is subjective but I prefer 10 to 15 minute games. I think at my level, playing bullet chess or even blitz doesn't make much sense and I don't find it fun.
I wouldn't play 30 minute games against randoms online because I already get enough salty players that run down their time because they just blundered a queen or are about to be checkmated.

"Best" has to be defined for any discussion.

In this case, I believe the OP is talking about one of three things: The best time-control for improvement; The objectively best time-control [Which, yes, there is no such thing]; Or your favourite time-control.

Many people use "Best" and "Favourite" enterchangeably (Which is very frustrating, as it is not possible to tell what they mean).

Not necessary.

I prefer increment only.

Yeah, I like increment games, like 10+5 or 15+10. Others I get flagged, so I don't play them.
