It really depends on what you use it for. For bosses you want high hp, and we need some for fast meat transport, poly transport etc.
For you reference, my best pre-imprint stats are: best hp 7198, best weight 688, best melee 300, ofc on different drakes =D
Usually the lvl190 egg is the trash... at least in my experience. But you absolutely cannot get a D-I-L-O-this-drake-is-born-with-10k-hp-without-imprint drake if you dont go for the highest level eggs.
