electrolyte is better than face shocker sry
but still it's heavily restricted to ranges as it's 2-4(imagine scope lovers)
For overall energy drone the backfire one is better but I don't see you have one.
On talking heat/electric, u got a heat monkey(that looks like gorilla torso), it's very tanky and useful when u are lacking modules (heavy weight with nice stats means lesser modules needed), and the nightmare is a contrary to it which is very light but needs several advanced modules to apply for max potential. ------Upgrade heat first (Dual desolation helps you counter energy mechanics since they are energy free.)
For now your mission is easy:stock up tokens, wait for 3k/4k token offer, try get more energy/heat engine module, and other basic weapons that start from epic
For starter on talking drones the backfire one is always the best as they deal decent damage and are no't restricted to range/turns.
Keep that nightmare, you will need it in later ranks.
Also keep the spark runners and Viking hammer they may be useful someday (who knows lmao)
