Pick for his age and his current obsession. For younger sons that means building, science and outdoor play; for teens and young adults it means tech, music and gear for what he already does.
Birthdays are personal, so the best pick is the one tied to what they are into this year, not a generic present. Kids care about the thing, not the price tag, so match the interest first and let the budget filter do the rest.
