An advantage of the newer package is the free number system. They're currently advertising that you can now use numbers from any Swiss network as your 3 free numbers. Which is handy (

) if your best friend is a stubborn Swisscom customer.
However in the small print, you will see that it doesn't apply to the Optima 30, 100 etc. But rather to the Start, etc. etc.
I'm planning on switching over whenever I get the chance to hold on the line.
