Generally speaking I think those plants fall into the catagory you are looking for. It really depends on what your expectations are and what you are comparing it to or judging it by. In general most stem plants require higher light levels than rooted, crown, bulb, rhizome plants, and respond much more favorably to C02 added to the aquarium. However C02 does make a difference with any type of aquatic plants.
Most of the common Cryptocorynes that come from Sri Lanka are easy to grow under most conditions. Only a few species require very specific growing condtions and some are really not suitable for any aquarium.
No matter what plants you choose, a certain minimal threshhold of light must be attained, and nutrients provided
