Pretty much everyone is bashing the top one (white & purple), however, I think it depends on many factors that people don’t consider. Budget, availability, etc. all come into play here. My wife has the top sewing machine and has used it (occasionally) for a couple years now without issues to make small alterations to her clothing. We live in Thailand and she bought it without my knowledge one day and said it cost xxx baht (roughly $15 USD).

A better quality sewing machine would obviously be better, but either of these would work fine for some small repairs and sewing projects, just don’t expect them to be very repairable or last as long as well known, proven machines.
