Not quite sure who you mean by "basic bitch" as you can pick any of them to level up as your first monster. You can only use one Monster at a time per fight but you can level up as many of them as you like. The Snake and the wolf offer the best damage just diffent buffs I prefer the snake for PVE due to my team comp but you cannot go wrong with either of them as your first pet really.
As you progress in the game you will find a need for different pets in each situation, the deer for example is pretty much a must have for guild boss fights post level 40. If you team is setup for a certain type of CC you can get a pet to compliment the build that offers the same CC, etc etc
