Aware on Altcointalks existence yet i had visited this forum when it was just starting but its been a long  time where i havent able to check it out.

When it comes to comparison then i cant say which is better but in the sense that this forum alone is the most known crypto forum then its
altcoin board discussion is much more worth to look upon.

Why would need to choose if you can have both? Its up to you on which one would really be useful to you.
