Like all drugs it's subjective innit. Personally I don't dislike oxy but I far prefer the high I get from morphine. However it just so happens oxy is what I currently have virtually unlimited access to while if I wanted morphine I'd have to pay extortionate DNM prices. Plus I get oxy off a trusted contact and don't have to bother buying bitcoin etc. Can't really get morphine on the streets here either only smack.
That said, and
@KS78 already put this well, it sounds like you're more into your downers as every drug you just listed there is an old school prescription sedative. I find it pretty amusing calling oxy out for causing OD's while saying Seconal was one of your DOC's though. It is very easy to die from potent barbiturates like Seconal and Nembutal, so much so that those drugs are massively in demand from people wanting to commit suicide. Nembutal in particular is also used by Dignitas. Yet you make it sound like barbs are a safer DOC than oxy? Haha.
Agreed with you regarding fent though. Most of the forum will agree. But that's got nothing to do with oxy. Just because some dealers are cunts who press fake pills doesn't change the effects of real oxycodone.
Regarding the constipation, I dunno how so many people get into so much trouble over opiate constipation. Just eat fibre, take magnesium supplements, and use Movicol and Dexedrine (or any stim, even caffeine or modafinil will help) to get things moving. Do all that and you can still shit like normal. And I only even need to use Movicol if I use opiates in the evening/night, like I am now cuz it's Friday, just snorted an 80, feeling the nod coming on and about to go for another. But weekdays I dose opiates only in the morning and when I do that enough of the opiate is out of my system by the next morning that I can shit normally without taking any laxatives. This goes for all opioids I've tried - codeine, DHC, tramadol, morphine, oxy, H, whatever. Then there's kratom which doesn't even cause constipation at all at least not for me.
But yeah basically I think oxy is overrated too but everyone's body and brain reacts to drugs differently and it's not difficult to see why people like it. I am guessing those who really like their oxy get a similar kind of high to what I get from morphine. In which case yeah it's right up there as one of the best feelings ever, a good opiate high is better than sex.
