It doesn't matter which one is better, as their position in the standings gives evidence of the better team. Although indeed, Barcelona looks better in the Champions League standings but that is still not a guarantee that Barcelona will be able to advance to the final match. So yes, for me personally Real Madrid and Barcelona are making good progress, because Real Madrid and Barcelona are in the process of building a team with a young squad. Although there are still some senior players, but the young players in their squad are still given playing time when the coach rotates for certain matches. Thus,they are making progress for the long term and it is a good way to make the team consistently compete in the top zone.
Yes, to be honest, it's quite difficult to determine who is much better, and the fight for who is better every time between Real Madrid vs Barcelona will never end, as happened with Ronaldo vs Messi, both clubs have their own super militant fans, and that's why there is El Classico, yes because the tension is that amazing at the match.
And to determine who is much better this season, just wait for the end of the season, who will hold the cups, both in La Liga and UCL.
