CoinURL or Coin-Ads? Which is the best?

Which is the best? CoinURL or Coin-Ads?

Those are websites offering shortening services and they pay you for each click. In both, the minimum cashout is 5 mBTC (which is a lot if your link is not popular).

Which pays more? CoinURL pays 0.00000050 minimum each click. Coin-Ads pays you 0.00000200 BTC each click.

Which is the best? CoinURL, in my opinion, is better about the design, functions, etc. Coin-Ads is good but doesn't offer many information.

About the user's vision, I think is much better CoinURL because you don't need to wait a lot of time to visit the link.
Coin-Ads pays more but you need to wait longer.

Which do I prefer? I use both :P
