In my personal experience, I have had the opportunity to try both marlin and swordfish, and I must say that they both have their own unique flavors. However, when it comes to comparing the taste, I would have to say that marlin has a milder flavor compared to swordfish.
Marlin, with its pink flesh, has a dense and firm texture that is reminiscent of tuna. It is a fatty fish, which contributes to its rich and flavorful taste. The high-fat content in marlin gives it a slightly buttery and oily flavor, which some people find quite enjoyable. The flesh also has a slight sweetness to it, which adds another layer of complexity to the overall taste.
On the other hand, swordfish has a similar texture to marlin, but it is lighter in color and has a slightly milder flavor. The flesh of swordfish is also dense and firm, similar to tuna and marlin. However, swordfish has a more pronounced flavor compared to marlin. It has a meaty and slightly gamey taste, which some people find to be stronger and more distinct.
When it comes down to personal preference, some people may prefer the milder taste of marlin, while others may enjoy the stronger flavor of swordfish. It ultimately depends on individual taste buds and what flavors one enjoys in seafood.
In terms of cooking, both marlin and swordfish can be prepared in similar ways. They can be grilled, baked, or pan-seared to bring out their flavors and retain their juicy textures. Some people also enjoy marinating these fish to further enhance their taste.
While both marlin and swordfish have their own unique flavors, the marlin tends to have a milder and slightly sweeter taste compared to swordfish. However, taste preferences can vary from person to person, so it is always best to try both fish and decide which one you prefer.
