Should I Play On?

MY game in this morning's second round of the Northumbria Challengers reached a critical moment in the following position:

White has just played 24.Ra1-e1 in Mark Waterfield (1609 Fide/1718 ECF) - Spanton (1808 Fide/1998 ECF)

As I thought about my reply, MW offered a draw.

What should I have done (apart from complain to an arbiter)?

I took the draw.

MW thought Black should play on with 24...Qxb2, meeting 25.Qd8+ Be8 26.Nf6+! with 26...Bxf6, hitting the queen.

I thought White would then win with 27.Rxe6?, missing that after 27...Qb1+ 28.Kf2 Black wins with 28...Qxa2+ 29.Re2 Qxe2+ etc.

The analysis engines Stockfish14 and Komodo12.1.1 point out White does have a win after 26...Bxf6, namely 27.Qxe8+! Rxe8 28.Rxe8#.
