Hello there, The Firefox Aeron 700C has a Shimano Claris 2-Speed front derailleur, a Shimano Claris 8-Speed rear derailleur and Shimano Claris shifters. They are not so smooth compared to the Shimano Sora gear setup, however, they are good for beginners. The Firefox Tarmak Is much costlier than the firefox Aeron 700C, however, it has a better gear setup and performs way better than the Firefox Aeron 700C. We would recommend both these cycles since they both perform well. If you are budget oriented, then the Aeron 700C is the best choice. If not, go for the Tarmak.
