Some number crunching.
1-E : 1000 credits, 13 tokens.
5-F : 4500 credits, 21 tokens, 1200 ship credits.
So, for 50% increase in energy, you get more than four times the credits (3 times as much if you account for extra energy), negligible tokens, but the selling point might be ship credits.
So, farming 330 Lando shards takes 1100 attempts, which will represent either 8800 or 13200 Cantina energy. You get 165 free every day, so assuming three energy refills to bring that to (360+165) 525 energy, it'll take 18 or 27 days.
If you go with 5-F, you'll get (1100*3500) 3.850.000 additional credits, and (1100*1200) 1.320.000 ship credits. Those come at the cost of 9 extra days of farming plus 27 Cantina energy refreshes (or 2700 crystals). For 2700 crystals, you can take five times the mega-pack of credits, which gives usually around 600k credits (rarely more, it's a gamble), if you really are in need of credits. So, the real benefit is a modicum amount of ship credits.
IMHO, farming 5-F is not worth the extra energy expenditure. There are plenty ways of getting credits, from Credit Heist to GW, and these rely on having enough characters.
So, pick 1-E. :wink:
Edit: and if you really need ship currency, buy them from Cantina store.
