I am a intermediate skier and l was wondering what would be better to buy or can someone explain to me the difference if any?

yes

Rounded is much better and you will find it is the latest technology in skis. Rounded skis help you carve the snow with ease. When renting go for the demos, a little more expensive but worth it becuase of technological advances.

good luck

It is mostly about fashion and style. While rounder tips generally mean deeper sidecuts and easier turning, pointed tipped skis turn just as well. l used to think the rounded tip was necessary to the design, but l was looking at some of my older skis the other day and noted that l have newer skis with a pointy tip that are wider and more deeply cut than a set l own that has a rounder tip.

a lot of skis have round or even square tip (some reno brand) so that it is easier to grab whilst in the air
