You can't say that one is better than the other. They are not the same type of anti-estrogens.
For some cycles, you should use Nolvadex, while for others, you should opt for Arimidex. It depends on what drugs you're using and what dosage of course. Example, if the only aromitizing steroid that you are using in a cycle is Dianabol and you're only using it at 20 mg's per day, you wouldn't need Arimidex, Nolvadex could be used and it would be all that you would need. At this low of a dose, some people probably could get away with not even using an anti-estrogen, but if you're sensitive to gyno, I would go with the Nolvadex for that example. Now, if you're using some form of Testosterone, Dianabol or Anadrol, plus others etc., it would be wiser to use Arimidex, but you don't want to use Arimidex if you aren't even doing much of a cycle, it would be a waste. It is very expensive stuff.
Liquidex is the liquid version of Anastrozole. Arimidex is the tablet version of Anastrozole.
These two drugs (Nolvadex & Arimidex) work entirely different, but each has it's specific uses in bodybuilding. Just b/c one is more powerful than the other doesn't mean that that is the one that you should go with. It depends on a lot of factors regarding your cycle. You need to tell us what your cycle is with the details and then we can help you decide on which to go with.
Research and learn buddy!
