Spiro cream vs Spiro Liquid

I’m looking to adding a decent anti-androgen to my current regimen (avodart + niz2%). The easiest obtainable one I can think of is Spiro.
Answers to the following questions from someone who is SURE of the answers is very much appreciated:

What are the differences between spiro cream and spiro liquid?

Which is more effective?

Which is the one members complain of having a stinky smell to it?

Which dried faster?

Are they both applied twice daily?

Does spiro work synergetically with any other treatment?

Thanks bros…
