Signatum vs Denarius

[Tipstar]

Both are unique algos and good with GPUs.
Which would be the better coin to mine using NVIDIA old GPUs?
Tried both, getting higher hashes for denarius.

I first hear of Signatum sometime last week and based on its thread here I feel that it has much more chance of making it big than Denarius. Though I admit I need to know more about Denarius and by the looks of it I need to research more before making a calculated decision.
