Ron got a brand new watch from Molly and ARthur, Harry's was second hand....except that Harrys watch was left by her brother Fabian who was a member of the OotP and killed in the first war.
On paper it looks like Ron got the better gift, but it seems that Harry got the more meaningful one. Molly had 7 children after her brothers died and yet she didnt give any of them this heirloom.
