I mean, if you want to be super efficient while still being newb-friendly, you could very easily go Isis or Bastet, both of which are super good early game leaders, the latter of which is an amazing lategame leader and the former an amazing lategame sub.
You could also go Horus for much, much more earlygame power but less lategame power in return. You'd also probably have to stick with his F/L form until you can safely make him Awoken.
And uh, not to scare you or anything, but his F/L form gave me PTSD. Just saying.
All three options are great though, since you have me for a good Horus Friend, Suikama for a good Isis friend and I'm pretty sure everyone here but me has an Awoken Bastet to help you out.
