I'm assuming by "best" you mean some combination of the most xp and perhaps not ridiculously expensive. Since there are no new gold-charm familiars, it makes sense to use those first so you can maximize the usage of the other charms. Making either arctic bears or barker toads gets you to 74. You should probably use your crims on Granite Lobs from there. You'd get slightly more xp by using something else to get to 75 and making Mantis, but I don't think the extra xp is worth the cost. This puts you at 81 with just the greens and blues left. What you do from here depends a lot on what you want to spend and perhaps if you want to save things. If you use all of your blues on Elemental titans, the most xp you can get out of them at 81, and then used all your greens on Hydras, again the most xp for your greens, you'd end up at 82. Fruit bats would be fairly cheap compared to the other options and the difference in xp isn't that huge, but you can make something else if the money doesn't matter to you. You might use your blues on elemental titans or obby golems, but you could also consider saving them till you can make lava titans. Greens aren't worth saving as there isn't really something to make later that would make a huge difference. So, TL;DR: Make Arctic Bears or Barker Toads, then Granite Lobs. Then, use your greens and blues however you want, depending on how much you want to spend and if you want to save them. EDIT: Looks like I was out-typed by some other people. I hope the logic of how I came to basically the same conclusion as their program helps you, or something.
