Fleet/Ship Advice

I really want to improve my ships and I'm not sure which ones to target and improve. I want to be able to get Tarkins ship to 6* and get to the final tier of the ship ability mats challenge.

Slicer is always worth powering up and you have KRU g12 already.
Imperial Tie & pilot can always find uses.
Boba is always worth investing in, though I wouldn't necessarily prioritize maxing Squish 1.

Ok ya my silencer is almost entirely maxed, except for the reinforcement materials and i dont think its really worth upgrading that since he is always in my starting group. I definitely want kylo's command shuttle since i have a pretty good phasma and nearly g12 zeta kylo. My question is, is it worth it to farm the stormtrooper and the ship? Ive also got Poe at 7* and cad bane is about to be, are their ships good? In terms of Boba and Squish 1 haha, I'm not gonna worry about him until I'm grinding BH's. Obviously to upgrade the executrix I'll need dark side ships, is tie fighter or cad bane better to farm up?
