I've played all int casters except Wizard to mid 50s/60.

Necro is probably the most enjoyable ride to 60. Plenty of milestone levels (20, 34, 49, 51, 60) where you really feel more powerful as you gain levels and spells. Tons of utility and different ways to solo if you get bored with one style. Low cost, high reward class. Being an evil race/class opens up tons of camps and opportunities too, that other classes might shy away from. Necro lets you embrace it!

Enchanter is #2. Super strong, but dies more often than other int casters and misses some of the quality of life perks of necro (FD, CoS, heals, types of gameplay). Incredibly strong though and makes a meh group into a killing machine. The amount of attention an Enchanter takes can burn you out, though.

Magician's next. I have a soft spot in my heart for Mage as it was the very first class I rolled on live. Pets are great leveling up and pull solid damage in groups or solo. The novelty of summoned items can be pretty fun. It can get a little old though.

Wizard I wont speak on as I've only made it to the mid-20s before getting bored. Wizards seem like they fell into the same spot as Rangers in that it took until Luclin/PoP to really give the class a good definition.
