I don't think it's a good idea to give a guy new to vaping something that takes technique and learning how use it. With a person new to vapes you would want the vapes without a learning curve.....
Well, we can let the OP make that call.
Dynavap was my first vape. Not that hard to get a quality hit and keep from combusting with a torch. Even easier with IH. And then you start dialing in your technique for the type of hit you most like. I've also given the Dynavap as gifts to non-vapers, and they've not reported any issues with learning to use it. Again, the videos on using it are extremely helpful, and you can really get a great idea of how to use a lighter and things to avoid etc from them. I send video links when I gift the Dynavap and while I got by just fine without having seen them myself, still learned things from watching them.
And from OP's list of criteria, his statement "I smoked pipes for some year so I love rituals, feeling tactile, portability" really suggests that learning technique is not going to be an issue, or that having to learn technique would be a complaint.
And these other criteria also continue to make me regard Dynavaps as an excellent option.
- I would like the ability to use small amounts of material;
- I love long, deep hits with long (minutes, I mean) breaks from each other.
