H5 “sample” content is by no means heavy… Its the SYNTH ENGINE in GRAIN or Synth mode that kills it… Specially with synths that have 8 OSC multiplied effects and so on.
Specially with combo patches that have 3 or 4 synths running at once per patch. Like the default preset that loads up. It has 3 Synths running and each has a ton of things going on.
Apart from that, it bugs a lot when doing programming.
WHICH is the main point of HALion. Its a Sampler… Just very insignificant commands in HALion have cause crashes and makes no sense to me.I don’t want it to crash when I’m programming for the last 30min. and a simple drag and drop would make it freeze or the annoying splash that an error has …blabla… etc… 
The sample content is very poor, Synths are great but very heavy.
Audio quality of HALion is the best out there.
ALL reported bugs need fixing, like last year… 
cheers! Lets see what H6 is gonna look like because the H5 UI is …mmmmhhh! not very friendly for programming unless you have 3 monitors or a 2k or 4k monitor. I can live with that… I just want it to be serviced with the long list of bugs.
