For arena, I'd say JKA is more useful in most cases. Lando is too easy to focus down because of his relatively low health. Though, I do run Lando in my arena team as leader because I want his speed boost for my STH. So, just kinda depends on what you're trying to build.
For GW, I'd say Lando is far more useful as his AOE is always available. I don't need JKA's ability block because I have TFP who can AOE that for me. Lando is also good for scoundrel/rebel events. JKA is good for tank raid.
I did Lando first because of scoundrel event. But, ultimately, it depends on what you're trying to build for.
I would say Lando depending how you are sitting with Scoundrels. If you can beat last tier of both scoundrel challenges and 3 stared the mod challenge already then Anakin is probably a safer bet.
Lando is still useful but is starting to lose steam imo.
Anakin is a better late game toon (high health, damage, tm gain), because Lando will get more suspectible to counter attacks and Rex leaders. Anakin also punishes everyone if he is not taken out immediately, which creates difficult situations for opponents to choose from.

Can confirm.
