How to compare data from 2 zip files and capture the new records from file2 to a new file

I have 2 zip files which have about 20 million records in each file. file 2 will have additional records than file 1. I want to compare the records in both the files and capture the new records from file 2 into another file file3. Please help me with a command/script which provides me the desired result in a faster way.

Example:-

File1 - a.zip

1,2,3

File 2 - b.zip

2,3,4
1,2,3

Required output

2,3,4
