In reading the description of this jacket it sounds like a bad choice. Maybe I am misunderstanding it, but it sounds like only the top portion is truly waterproof and the bottom portion is soft shell. This sort of hybrid design is very, very good in specific use cases (think ice climbing) but bad as a general use shell.
Soft shell, regardless of whether it is the waterproof (membrane) variety or not, will absorb substantially more water than hardshell material. It's also likely to not be waterproof as many sorts of soft shell are not.
When I think about buying a hardshell I think to myself, will I hate it if I'm forced, by heavy rains, to wear it all day? Will it keep me sufficiently dry to justify carrying or wearing it? I don't see the answers to those questions being positive as far as backpacking is concerned.
Now, if you asked me if I'd like to go ice climbing in this jacket I'd probably say yes.
