Which Tyres?

Hardcases are totally fine tyres, 'guapo runs them with no problems at all. At the end of the day the tyres which have been recommended to you are all fine, some people may prefer one over the other but that's just personal preference. None of them are going to blow up and kill you in the face or anything unpleasant like that, unless they are Continental. Just buy one and if you like it buy it again when the current one wears out, and if you don't like it try a different brand/model next time.

Fixed.
