First G shock

Would this be a good first g shock? I have a Casio f91w and the lf20w. I would like to get a g shock and noticed this for $45. Otherwise there is a GWM5610-1 model that is tough solar for $104. Is it better to save and get the tough solar or just the picture one for $45 good as a first g shock? I like the rectangle style over the round.

Thank you!
