I second that comment - your particular environment will have a big impact on what plants do well. Where I live, sometimes the summers are humid, but for the last 3-4 years they've been very dry. Some of the 'easier' species pitcher poorly compared to others in those conditions. Further, some species will grow brilliantly for me for several years, then sulk for several years, then grow well again etc.
Another thing to remember is that a lot of information around is dated, and arises from those species that have been in cultivation for a long time. Accordingly, alata, maxima, ventricosa and sanguinea get referred to often as very easy to grow. But those species have just been commonly grown for a long time, so have built up this entrenched view, because they were being compared to the relatively limited pool of species that were in common cultivation.
Now there are many more species available, and some species which were rare (which people often associate with them being difficult) are now common, and easier to grow than the traditional favourites in certain types of conditions.
All I can say is, try anything that would generally fit in your local conditions, and see if it works for you. What may be a pesky species for someone else may be a breeze for you, and vice versa.
