They look good, although if you want to run longer forks then a Ragley might be better.
Not a replacement for a full suspension bike though, nothing is. Riding in the lakes you really will be using the rear suspension, whether you can live without it is another question.
Most reviews you see of these on the forums seem to be from people who build them up with huge forks and then mince round trail centres on them.
Or buy one as a second bike (to compliment their full suspension) cos they’re cheap and then realise that they were infact were completely over biked with the full susser and that the C456 is actually the best thing ever.
So you’ll get lots of glowing reviews, none of which will be particularly useful.
