Not really. Nightwing Year One is about how he got fired by Batman and created his own NW identity, whereas Robin Y1 is about his first year as Robin with the whole Two-Face and Shrike debacles.
You might like Nightwing Year One. Lots of cute Babsgirl/Nightwing moments, Bats messes up hilariously, Alfred is awesome and Jason annoys the hell out of Dick. Real cute. I liked it more than Robin: Year One.
