Wall hung reviews

Any advice on whether to use wall hung toilets in our construction? We framed for wall hung but they seem expensive and I can't find any reviews of Geberit or Duravit that reassure me they are worth the expense! After reading some of the reviews on this site I am hesitant to buy without guidance.
Thanks!

Porcher good

We have had the Porcher which was costly but has worked like a dream for years. So much more convenient to clean under.
