I've tried both, and both won't give fast results if you want to grow your penis. In fact if you use them alone you'll probably have to wait a very long time before you see any gains.

In terms of effects, tongkat ali gave me the most noticable libido boost but it was very mild, I needed very high doses to see a change.
Butea superba doesn't seem to be very effective for me, hardly any aphrodisiac effect at all.
I find that food and drinks have the biggest effect on boosting PE gains. Anything that will improve blood circulation and dilate blood vessels is good, eg: Chilli con carne, ginseng, ginger, gingko biloba. These are easily available and cheap.
