is casement or sliding windows better for kitchen? Any major price differences?

I like casement since they can all be opened up but i am worried in future after wear and tear the window might fall off! Also you'll get your hands all wet when closing them when raining. For sliding windows, i don't fancy cleaning the 'tracks' as they collect dust but they seems 'safer' on a long term basis.

Any advice?

If I had to do it again, would have done sliding. Casement hinges can be hard to open, plus you need to stretch outwards to open fully. Also has tracks to clean. Handles tend to loosen over time, need to constantly tighten.

Thanks for sharing!
