Should I watch episode 23+24 of the original series before steins;gate 0?

No spoilers please, spoilers are probably the last thing I want around now!

Context: Currently at episode 12 of 0, and I'm wondering if it's even worth finishing, as I'm not enjoying it nearly as much as the first season. Many people have told me steins;gate 0 ruins the original series in terms of character developement, so I can't decide whats the correct thing to do here. Please help!
