Should I finish StS1 before getting StS2

This is kinda of dumb and also completely subjective but kinda wonder what y'all are thinking abt this. On A19 with IC defect and Watcher + have like 4 more achievements to get 100%, my goal was to get A20H win with each character (alr did with Silent) and 100% game before getting Sts2 but work has been too busy lately. Anyone else feel like this or are y'all thinking just jump on to StS2 and see whats up in the early access then go back to StS1 later
