Taking Bike on Train Nice to Paris

Hi,
I am finishing an Alps trip in June in Nice, my flight back to Asia is from Paris.
Would you recommend flying from Nice to Paris or taking the TGV from Nice to Paris.
Is it easy to take the bike on the train (in a bike case hardshell?).
Any advice apreciated.

once in paris you still have to get to the airport, i wouldn't take a bikebox on the metro/rer
i like travel on the tgv, but i'd still fly from nice to the airport for your onward flight, it'll be faster and less hassle
