I think the second ult is slightly better just because the first one seems overpowered. True damage is pretty strong and 30-50% is a rather hefty scaling.

Some good stuff but generally seems too strong as a champ. Comparing like for like you've buffed his passive, q, w and e, arguably his ult isn't a buff but even so this would be really strong.

As a concept it seems pretty solid, you could just tweak the numbers to make him balanced.
