5 punctures in around 600 miles meant that the Ultra Sports on my new bike went in the bin a couple of weekends ago.
To give you comparison:
6,500 miles on the Bianchi , 5 punctures over two sets of tyres (a mix of Vittoria and Armadillos) all running at max pressure.
The new bike is now shod with Dillo's.
I've never had the valve-making-a-bid-for-freedom problem some have mentioned.
I've never used Decathlon's bargain tubes.
Mostly Specialized, and more recently Michelin and Bontrager.
If you check your tyres for embedded foreign objects and pressure regulary, I'd not expect you to be puncturing as often as you seem to be.
