Well, there are so many things at play here. What's best for Howard, what's best for Orlando, and what's best for the Lakers.
As a Los Angeleno, I can tell you the Lakers desperately want a post-Kobe star. Lakers High Command would never be content with a Nuggets or Sixers-style team (even though plenty of fans would). They want stars.
So, Howard certainly checks that box. Howard is also a couple notches above Bynum as a player, so a Laker core with Kobe, Pau, and Bynum is probably 3-4 wins better than the current core.
That said... the Lakers have HUGE holes at PG, SF and the bench. Holes that Howard alone can't fix. Holes so big, that in the long run of this season, they make a Kobe-Pau-Howard core not all that much better than the current one.
So, I don't know. If Howard is savvy, he sees this and thinks, "Hm, maybe LA won't get me that ring all that much faster than Brooklyn would, consider Brooklyn actually has cap room..." Then again, at no moment of this "process" has Howard demonstrated anything resembling savvyness.
