Aromasin is a better choice for PCT IMO it lowers estrogen, raises free test and IGF-1 levels. It does takes a little longer and has a shorter half life than Adex. Unlike Arimidex, Asin is a suicide inhibitor so there's less rebound estrogen effect when stopping. Price is higher in the long run since the recommend dose is 25mg ED.

Arimidex levels rise quicker, around an hour, with a 40+ hour half-life. Adex doesn't inhibit aromatase it competes with it at the receptor level. Neither will "trash lipids" alone and the recommended dose 0.25-0.5mg EOD makes Adex infinitely cheaper to run. I prefer Adex for estrogen maintenance on cycle or in my case forever.

In simple terms, Asin for PCT since the rebound won't screw you up when you stop and the estrogen suppression is 70-90%.

Adex for TRT or on cycle since it works well with slightly less suppression of estrogen. I personally prefer to be a little "wetter" when bulking and Adex is orders of magnitude cheaper :)

With Aromasin havinga shorter half life than Arimidex do you see any fluctuation in e2 running it EOD? Have you ever ran it ED?

I run 12.5 mg 2x a week when on blast (for me a whopping 500mg per week of test) and can be good with 1x a week or even none if I drop the trt dose low enough (150-200mg E5D). I just take the stane the same day as I pin to keep it easy.

I have had blood work to prove the numbers and feel great.

None. I have never had to run more than 12.5mg EOD. But I don't really do high dosage cycles. For example, right now I'm on Test E, EQ at 750 and 600 and 30mg of dbol per day for the first 5 weeks. If I went much higher this might change.
