Hey Aleksandra - We have sponsored both the conferences last year. It comes down to few things -

1. Where are you based? If west coast go for the ProductCon SF. If East Bay then both have one in NYC.

2. Industry is spread across 3 days. ProductCon is 1 day. So time in hand is another factor.

3. Lastly Industry has workshops if you are interested for that.

Hope this helps.
