Any suggestions it's will be better. Thank you

What "last survey" - by whom? when? Give a link!
"The 8051 has been around since 1957"
Nonsense! The integrated circuit as we know it was not invented til 1958!

"The pic has been around for a long time too [1989]"
That sounds a bit late? en.wikipedia.org/.../PIC_microcontroller suggests 1975
"The avr is newest [2003]"
Another bad date: en.wikipedia.org/.../Atmel_AVR

My child has better manners than you! If he spoke like that to me he'd not even wait for me to tell him to go sit on the naughty step!
