The difficulty is mostly based on level of competition. In F1 ladder, because of international talent pool, there are more hopefuls trying to earn their place in F1, but ultimately less seats available for them. 20+ vs 43. Think about it. If there were more NASCAR hopefuls than F1 hopefuls, with only 10 available seats in the Cup series. The same thing.
Hell, if somebody still wants to argue: F1 dropouts can move to NASCAR. Does anybody seriously think any of the F1 teams would accept NASCAR dropouts? Especially the ones without past road course/open-wheel expertise? Hell no.
Because of these factors alone, F1 ladder is tougher to climb. Of course, if you want more than your place in F1/NASCAR, then it´s different situation. Getting to NASCAR may be easier, but actually beating JJ for the title isn´t.
When it comes to sponsorship, keep this in mind: it is not merely about money needed - it is also about money available. In NASCAR ladder, the budgets may be smaller, but that doesn´t mean collecting the required money is any easier.
So that´s my take. Please, "I think NASCAR is thougher because Juan is there now" squad: I am not saying one series is better/more demanding than another (re-read my point about beating Jimmie). I am merely pointing out F1
is more "exclusive", mostly because there are so many candidates and so few seats.
