Big 4 Corporate Finance vs Family Office after 1 year?

Currently at a Big 4 doing corporate finance/M&A. Been here for around a year, mostly working on sell-side deals.

I recently got an offer to join a family office in SEA managing a few hundred million USD. They invest across public markets, funds and direct investments, but from what I've been told I'd mainly be focused on the direct investment side which includes looking at new opportunities, DD, modelling/valuation and monitoring existing investments.

Long term I want to be on the investing side rather than advisory, potentially PE or an institutional fund down the line.

My main concern is whether leaving Big 4 after only a year is too early. Would it be better to stay another year or two and get more deal experience, or take the opportunity to move to the buy side now? Is family office experience valued in other investment roles?
