@glimpsing yes, ah for unity! But life would be boring without a bit of diversity of thought and, in the end, like you I think we must concentrate on the goodness and love of God and stop making hell a stick to beat people with; we've done that for far too long, and the trouble is that it makes God the stick bearer. My issue with the hell as eternal separation from God position is that separation from God means separation from all that is good, beautiful, perfect, kind, safe, loving, and therefore in itself is great loneliness and torment. For me that's just the same as burning in fire for eternity.
@MissingSummertime sure, of course. In fact, the texts you've given are proof texts for the conditionalism perspective (ceasing to exist.)
Matthew 25:46: Jesus talks about eternal punishment, not eternal punishing. The clue is both in the verb form and also in the Greek translation of 'eternal' which comes up several times in the NT in the context of something that has been finished but has eternal consequences: for eg, eternal salvation (we don't keep being saved forever, it's done). I'm not arguing for no judgment/punishment - Jesus uses stark language because of the seriousness of evil and oppression, and I think we can all identify with the need for justice for all the atrocities of centuries, right down to the tiny little things that hurt us and others every day (ie sin.)
Rev 14:11: the 'smoke of their torment rising' is used several times through scripture as a hyperbolic statement to show the finality of something (ie the consequences lasting for eternity.) Indeed, the exact thing is said for Sodom and Gomorrah, and we don't see the smoke rising of those cities now - it was poetic language of justice and judgment on great evil. They always say you should use the Bible to interpret the Bible, so we must look at the bigger picture. The same goes for 'having no rest day or night' - a hyperbolic statement, normal for the context of the book, that doesn't name a duration and in fact on careful study is to do with the time on earth when they are 'worshipping the beast' or having the covid vaccine as my relative would say 
Rev 20 - couldn't be clearer. What is the second death? This is a plain reading. Does the second death mean people being tormented for eternity, or does it simply mean what it says it means - a cease of existence? What usually happens when someone falls into a lake of fire? - now I know this is all new and a bit scary when you're so entrenched in a traditionalist position, but to me it was an eye opener, and I also came to realise much of the language simply communicated God's abhorrence for evil and the suffering that mankind causes, and the writers therefore chose very stark language to communicate this. But nowhere in that passage does it say they were in there forever, tortured by little devils with forks.
Also in Matthew 10:28, Jesus says: “And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
Exactly...see what I'm getting at? This verse is plain reading. It doesn't say fear him who can torment you in flames forever. It says fear him who can destroy both body and soul. That's pretty plain to me in terms of the duration of the punishment. And again, Jesus is using stark language to express a great sadness at evil and oppression.
I have no idea what Hades or the 'intermediate state' is, but I don't think it matters, the Bible doesn't explain it (it talks about Christians going to sleep). I do think we use these ideas of darkness, fire and torment as sticks to beat people into submission, and I think that's not God's heart at all. Jesus talked a whole load more about oppression than gehenna, and used gehenna as a reminder of past atrocities and the nature of death, to give people the chance to repent and choose a new way of love and salvation. I do believe Jesus saves us from death (John 3:16 says it plainly as do many other passages), but I don't find any grounds for the medieval construct of eternal hell. However, I can see how the pictures used in scripture were twisted to form such.
As for testimonies, there will always be testimonies and it's very difficult to trust people when there are such differing ones. It's like near death experiences - people in different religions experience what they expect. I tend to be a bit sceptical about these, but maybe that's my issue.
