There are actual math studies that prove this, it's not really an opinion thing. OBP is worth about twice as much as SLG, like the other poster stated As another example, take one team with a .300/.500 split, and one with a .400/.400 split. Though both teams have an OPS of .800, the first team is expected to score 4.9 runs per game while the second should score about 5.8. This suggests that, in many situations, trading slugging for OBP could be a good idea. https://sportsstatsanalysis.wordpress.com/2009/06/10/whats-more-important-obp-slugging-or-ops/
