I feel that both choices are going to be just as bad. Novus is the easier of the 2 by far. Money can be made and time can be used, but it can't hold up to the many hours and sleepless nights of T9 progression. If you want a "Decent" weapon, and I use the term loosely, the UAT/Sol weapon upgraded is by far a faster choice with the addition of hunts. Its a "good" Weapon for all classes, and in some cases has better stats, but is it and can it ever be better than novus or HA? Not by a long shot. Stat customization makes Novus more appealing and HA is just BiS for any job. It really comes down to what YOU want, and what YOUR willing to say is "good enough". And to be frank, you can do all content in the game with a Levi or Ramuh weapon, bar SCoB.
