Damn. Not much of a difference though really, both are admitting to what you got popped for.
With the no contest though, you can't be brought to trial again for that incident.
Go to traffic court though, hopefully you can at least one of those three dismissed. I don't know how it is down there, but I had to go to Alameda traffic court and the commssioner was dismissing/reducing hella people's shit, even shit like yours.
Damn bruh, you should be driving like a grandma though if you're riding dirty ! Haha...
Good luck though.
