I personally prefer cloth-backed diapers over plastic ones. I once bought some plastic-covered/backed ones as I had no other option and I experienced discomfort from heat and problems re-adjusting the tapes as the plastic began to shred. Maybe they were of bad quality or I did not know how to use them properly. However, it was a real problem as it was difficult to got to the toilet as the tabs were not re-adjustable, or could be re-adjusted only once, which ensued in very uncomfortable situations
. I was abroad then and had to experiment with a brand I did not know and was still new to the whole business of wearing. Luckily I managed to find some familiar brands and after learning the locations of public toilets in that town I had no problems. 
I like the fact that cloth-backed diapers breathe, are very discreet and do not crinkle, but as I luckily am not a very heavy wetter nor have accidents on a regular basis, I don't need the extra protection offered by PBs. Personally I've liked Molicare's and Tena's Slips the best, but I don't know if people disagree. I guess it's a matter of preference and suiting your needs.
Oh, and merry May Day, (May 1st) to all of you who celebrate it!
But again, thanks for your insight. 
) and they have been pretty comfortable. I just wish they had lower absorbencies on their selections, the M3 is a bit of an overkill for me (maybe if I asked them nicely they would start carrying those lighter products too).
