Good morning Pam!
Contrary to what you have been told pine is not an unstable wood. It is softer and you will see denting, scratches, etc in the flooring. Most of this can be held to a minimum by simply following some easy rules. Keep your floors swept and put rugs at your doorways to trap sand and dirt and put protectors on the bottoms furniture that you move often such as chairs,to prevent scratching. Take your shoes off at the door. High heels are particularly hard on wood. There are many more things you can do to help prevent damage.
As with all wood you should keep a relative humidty level but your floor is not going to cup simply because it got wet. If you spill something, wipe it up. Never leave standing water and don't wet mop your floor.
If you can find a wide plank engineered I would go with it for the added stability factor. The chances of cupping in any solid floor increase the wider the board gets. I sell Authentic Pine and I know they have wide plank in both solid and engineered versions. (authenticpinefloors.com) Pine is a beautiful material and only gets better with age. If your still not sure how well they'll hold up go check out the floors in an old plantation and see for yourself.
As far as the rustic cherry goes it is pretty but I am not a fan of all the short boards you get in that grade of material. You can get it in longer lengths if your willing to spend the extra money for it but I like the pine.
