Should I teach my Croconaw HM3 (Surf)?

Question

I heard that Surf was very powerful, and I'm playing Pokemon HeartGold right now. I want to teach Surf to my lvl. 29 Croconaw, but his moveset is full with Ice Fang, Bite, Rage and Water Gun. Which move should I forget and replace with Surf, or should I just not teach Surf at all?

Answer 1

Surf = 95 BP
Water Gun = 40 BP

Therefore Surf >Water Gun.

I say replace Water Gun. It's kind of a no-brainer, really.

Answer 2

You should replace Water Gun with Surf.

The reason for this is pretty simple. Surf has 55 greater BP than Water Gun.
Why I don't suggest replacing Rage with Surf is because, although it has low power, having two moves of the same types doesn't really accomplish anything in-game. Later on, you can replace Rage with a different move.
It is also necessary to have atleast one Surfer because you'll need it to progress further in the game.

Answer 3

Definetly get rid of water gun. Surf does way more dmg (base power of 95) and it also hits multiple Pokemon not to mention you'll need to to cross large bodies of water. Besides Croconaw and Feraligatr are phyisical hitters so it's a good thing you have the other physical moves to abuse its attack.

So yes replace Water Gun with Surf
