hardiplank vs cedar

i need to replace quite a bit of wood trim on my house, it is painted
cedar now. eave trim will be cedar for continuity, but if i replace
an entire window box, should i do it all in cedar or hardiplank? its
cost vs ease of installation, i will do it all myself. it just seems
easier to cut and nail cedar.

any input? i plan to sell in 2 years.....

I've put up a ton of Hardiplank. It's easy to handle, cuts nicely, nails
well, and takes paint wonderfully. It won't rot or be eaten by termites

I've used hardiplank and must say I really didn't too much of it.

And was told by the lads at the lumber yard that it is not as
waterproof as the manufacturer would have you believe.

I would stick to the cedar and remember to prime both sides.

It really does make a difference in how long it last and how long
paint stays on.
