Dub vs Sub? Why not Both?

I never understood it, why would someone limit themselves at best and demean the other side at worst when you can freely flow from one side to another?

I follow the very simple logic of just watching whatever sound better to my ears, sometimes the moonspeak doesn't sound good to my ears and the dub wins out, but if the dub factuality sucks or I don't like the main voice for the MC, I stick with the sub.

If an anime is really good and I go for a rewatch, I usually go watch it in the language I didn't the 1st time.

Of course there are exceptions, I'm an English speaker so I'm biased. Fullmetal, steins;gate, code geass and many more, I will never watch in Sub cause the dub is just that iconic and wise versa. AOT, Mobpsycho, Dandadan, and usually animes with Japanese englrish, I will only watch in Sub, though I did listen to the Dub to make that decision.

And for the crowd that says, "I don't want to read." I feel sad for them cause reading is fun, I like reading so much that on American shows and movies, I turn on Subs if I can. Or even if I'm watching Dub, this site lets me turn on subs and I'm doing both and having a blast! I've never used a site with that function before. And I was a C class student who never did HW, so don't hit me up with that "nerd" bs just cause you cant find the joy in reading. And for the crowd that says, "I'm too busy reading and missing the action." read faster? Again C class slacker and I don't want to be mean but like come on, this cant be hard right?

Reading is fun and the Dub can slap too, why cant people free themselves?
