It probably depends on the BigCo... I'm happier on the product side of the fence at my current BigCo gig than I think I would be on the support side, though at somewhere like Google with a strong SRE culture and a tendency to kill many products it might be the other way around. I'd probably be happiest if I got to do a bit of both again, but BigCos love specialization. Though even within a BigCo it just depends on the team sometimes. I talk to a few people who are very happy on the support side, much happier than being in product before, I also talk to others who aren't at all happy. I've seen teams and managers evaporate on both sides too. In my sample of one the biggest sources of frustration on either side seem to be the priorities of upper management, and there can even be mutual frustration. Like some people on product will get annoyed at support people for not providing enough support in something (e.g. test automation infrastructure), but support people are equally annoyed at not being able to provide enough support because upper management decided to shift more resources to product.
