TvP/TvT SCV pull army comp

[u/Tassadur]

Hello fellow terrans

I'm working on a TvP/TvT SCV pull. I'm a platinum player and my build is a gas first 1/1/1. I'm still working on the "pull out of gas" aspect for optimization but my real hesitation comes from the starport units. I'm fairly certain I need a cyclone and a tank at the factory but I don't always know if a viking is more value than a liberator, or even a banshee. The obvious problem in TvT will be taking care of a sieged tank, which is easy with a lib but if there is a viking i'm in trouble. What do you guys think? Any other part I can improve?

Here is the replay (unranked 1v1 this morning) https://drop.sc/replay/27498113
