Mage earth pet 49 vs 51

[murcielago200]

Greater Conjuration: Earth 49 41 3075 56 ? 0 30
Vocarate: Earth 51 45 3150 58 ? 55 30

Going off this the level 49 and 51 earth pets are very close in starts.
I can use focus item with level 49 pet(shovel) but I can not with the 51 pet.
Which pet is better? Since they are so close already I would guess the 49 pet ends up being better until I am able to get a new focus item.
Has anyone done testing on this?
