hi, i have different experiences, i rather use petg than acrylic, it will break easier and is hard to bend and cut. a mess
It's individuals preference and motivation. I'm no genius in tub bending nor cutting let alone dealing with acrylic and I admit I wasted few good pieces of beautiful black tubing, but once you get use to it and are aware with when you might run into difficult moments e.g. overheat of tubing and potential bubbling, tub it's not preheated enough and premature attempts of bending causing to ripple or just the complexity of your tube routing can be frustrating, but once you get the hang of it there is nothing difficult about it, but reword is great.
The fact is that acrylic will last your for years with any liquid and does not absorb any liquid, unlike PETG does and will not last that long.
As far is cracking? it does not crack, unless you drop it, oppose to PETG dries out, believe it or not and that's where the restrictions and limitations of liquid choices comes from.
I have very big 2 loop system with acrylic tubing even in the basement to keep it clean, yes it took me a while to finish it, but it's been 2-3 years now, it's perfect and again I would personally never chose PETG, but that's me.
Btw. I'm not DazMode fan, but his video regarding PETG and his research "white sheet" of compatible liquids is very informative I have to give him that, he did good job
