To evolve or not to evolve

Will my s trunky be as powerful if I don't evolve him into chunky? Or do I need to evolve him for him to get the best stats? The reason I ask is that trunky is so cute and chunky is well, just not

Thanks

You will miss out on 30-50 overall stat points increase:/ You will do best evolving him.

Thanks, that's what I needed to know. It's a shame as trunky is so cute
