Which Canni is best until Lv58?

[Slonekb05]

Canni 1: 50hp=(Lv24) 20-28(lv60) mana
Canni 2: 67hp=(Lv34) 30-36(lv60) “
Canni 3: 74hp=(lv54) 34-38(lv60) “
Canni 4: 148hp=(lv58) 81-82(lv60)”

Hey there, sorry if this is really obvious, just want to be sure. Okay so Canni 4 is clearly the one to use once you hit lv58, but what about lv’s 54-57? I get from the wiki that at Lv 54 Canni 2 vs Canni 3 is a speed vs efficiency .. but is that the case till lv58 or just on lv54? Also .. would Canni 1 be in this conversation as the most efficient until 58? Any wisdom on this is appreciated. Thanks
