Tyres will vary in profile shape, construction and rubber compound. These will affect how comfortable the tyre is, how it handles, how well it grips and how long it lasts.
Puncture protection will also vary. Outright racing tyres will have pretty much none in favour of super-low rolling resistance and weight. They will also tend to wear very fast, but give outstanding grip.
Zaffiro's are considered an entry level tyre, but a good one. Vittoria are one of the most popular brands along with Michelin, Continental and Schwalbe.
It's a popular topic on here and everyone has their favourites. Personally I like Continentals, GP4000S and GP 4Seasons for excellent grip wet or dry, a good ride, good puncture resistance and long lasting (my GP4000S are at 3000 miles and plenty left in them yet). They are not the cheapest though.
Other commonly recommended tyres are:
Michelin Pro 4 Service Course
Schwalbe Durano
Vittoria Rubino Pro
