Boot-time scan vs normal scan

Which of them runs faster,or, which one needs less time?
also, which of them detect viruses better?

Note: just wanted to know…

In My Opinion…

Boot-scan is better but takes more time to finish compared to a normal scan^^

“Maybe” avast! scans ur PC while the possible malware is not running^^

like not running on startup^^
