I'm not going to judge which one is better (though I personally prefer espresso, it's a matter of preference), but coffee brewed with different methods definitely tastes differently. Coffee brewed at higher pressure (3~4 bar for moka pot, >9bar for espresso) tend to taste way stronger and more flavorful (which is why they're drank in lower quantities)
But as mentioned I don't really have a horse in this race to begin with. Drink what makes you happy however you brew it. :)
