As far as the V1 vs V2 debate, I for one am more inclined to the V1 version since it felt like the Resistance absolutely failed and that their destruction of SKB was out of revenge. Almost like a “Remember the Alamo” type of situation.
Having SKB just immediately start targeting the Resistance base almost makes out the First Order to be too good at what they do. I like the idea of them being almost like children trying to take each others toys away. SKB destroys the Republic, and then the Resistance destroys SKB out of spite and revenge.
Just my 2 cents
