Evade Window vs Evade Extender

Hey Hunters! I'm new to the franchise, (about halfway through iceborn) and I'm really enjoying evading and reacting to monsters through dodging! I'm curious which is more effective? Should I stack both?

Also, do we think DB or SnS are more effective "evaders"? Is there any reason why one weapon would utilize evade better than the other?

Appreciate the help! This game has jumped to a top 3 game of mine in such a short amount of time. Can't wait for wilds!
