Wow, this post and you're claiming my simple question is trash. Go home, son, you fail.
First round in the NBA is the first half of the draft. NFL is around the first eighth or so. Add roster size and the vast MAJORITY of NBA players are first round picks. In that case, the first round NBA picks are more valuable.
If you want to add half the NFL draft to coincide with the full first round of the NBA draft, the last half of the NFL would yield a better team than second round NBA picks. In that scenario, first round NBA picks are more valuable.
If you want to drop the NBA first round to the picks that coincide with the NFL, the first 7 picks, then the first seven picks of the NBA draft are more valuable than the first round of the NFL draft.
The top players in the NBA influence their team success more than the top players in the NFL, therefore the picks they're selected at are far more valuable than fit into a coaching philosophy. So much so that players selected a third of the way through the NBA draft are more valuable than the players in, say, the first sixth of the NFL draft. You fit your coaching philosophy to match the players in the NBA. A first round pick in the NBA is more valuable than a first round pick in the NFL.
