I have checked out all the resorts you have mentioned in Tulamben. None are as nice as the resorts are in Amed. We stayed at the Tauch Terminal and the deluxe room smelled of sewage (my wife was choking on the smell that reeked out of the bathroom drain). The WiFi did not work most of the time over many days, and when it did work, it was so slow it was nearly unusable. The service was non-existant or terrible (depending on if you actually expect any room service), for example, you can't even pick up a phone and call for an extra towel since there are no phones in the room. So any request is a trip to the front lobby, which is not our idea of "great", sorry! We don't like broken WiFi, sewage smells, poor room service, etc. But many people don't care as they just like flopping off the back of the property and diving the Liberty Wreck, which is OK if you don't have a car (and little other choice).
Amed is nothing like you described. Yes, there are tourists, but there are also great divers and dive centers there. Amed is much better than Tulamben for anyone who prefers a higher standard of rooms and great place to eat, and has a car. If you have no car and just want to dive Tulamben, and food is not so important and resort quality is not very important, then obviously stay there...... we have higher expectations, sorry.
I have stayed in Tulamben and have visited (almost) every resort you mentioned and, personally, we found the best resorts in Amed heads-and-shoulders above the best in Tulamben. I could easy name names, but I'm not posting to promote certain dive centers and resorts. I am simply telling you that I am a diver currently situated in Amed and came here after staying in Tulamben, very disappointed in the quality of service in the resorts, WiFi, and food there.
OBTW, in Tulamben, independent DMs hassled us on the street (begging us to dive with them and even followed us to local restaurants begging us to dive with them) and touts troubled us at nearly every turn, they even sell on the beach next to the Liberty Wreck. We never experienced this aggressive behavior in Amed. We have been here for nearly three weeks, BTW, this month.
We are in Tulamben (diving) and Amed (diving, eating and sleeping) now and what you describe is nothing like our experience! There is no point in continuing the debate in public, especially since you said "go to Tulamben and leave Amed" as if I have not been (LOL) there or any resorts you mentioned. Have been to most all of them, either staying there, having dinner or visiting the rooms checking out the WiFi and quality of the rooms, bathtubs, beds, etc , ROTFL.
Good Luck and Happy Diving. (Glad you are happy in Tulamben, but not us! We day trip for the Liberty Wreck from Amed and are very happy doing so and will not change our minds. We love Amed so much.)
