MSc is an academic degree. It's more valuable than M.Eng and gives an opportunity to pursue PhD afterwards. In contrast, M.Eng is a professionally oriented program. It takes less time to complete M.Eng in general. So, both programs will lead to a career in industry. If you want to go straightforward to a work force and not considering Phd in the future, I'd suggest MSc since it's faster and you'll study less.
