Absolutely not high end, so if it came off that way it was in error. If I wanted that I'd go to Meridian which seems like the most hotel / comfortable of all. Prefer a hut on the beach with a shady place to nap and listen to the ocean. The rooms at Bio actually look less hi end than Papua Paradise.I enjoyed the food and didn't find the diving chaotic. Regardless it sounds like you want a high end beach resort which you will not find in Sorong. Bali is probably your best bet for that in Indonesia!
I am only going on the word of folks i've been traveling and diving with for 30 years
