Cephs are easier for me in my growing conditions. Heli's are a very different story:
I once had three species and hybrids of Heli's and they never produced one adult pitcher in 2½ years of "growing". I could not get my conditions both light enough and cool enough for Heli's I guess. Plus the high humidity requirements encouraged far too many molds, fugus etc.
I had to sell/trade them away a while back. Too bad too, they're such beautiful plants when grown well.
I'm envious of those that CAN grow Heli's well.
