astable multivibrator with555 compared bjt

Well, for one thing, a 555 chip is a lot easier to build up. It's probably a lot more stable than a discrete design.
It all depends on what you are going to do with it. For sensitive measurement instruments, I would never rely on either one as a time base - like taking ADC readings, for example.
There's a lot of stuff on the web about discrete designs. Try looking at

Agreed, accuracy and many fewer parts. Plus it does a lot more, like PWM.
