If you like to SOLO charming more than anything, I'd definitely recommend sticking with necro.
Enchanter is good at killing solo but really shines when duoing with some kind of support class such as cleric or shaman or druid, etc. You can charm both living and undead and are a lot better at breaking tough spawns but the drawback is that if you get a bad run in with the RNG you'll have to sit on your butt regening back HP for a long time, die or cap out.
Necros have the very big get out of jail card called Feigh Death... Not to mention that you can heal yourself with life taps, significantly reducing downtime. It's a much more laid back class to play when soloing.
I would recommend playing both to about level 40 and just pick the one have most fun with. By 40, both classes are sufficiently representative of what they will be at 60 when it comes to charm soloing to make a somewhat informed decision.
