Hi, I have the TT Notch, I was drawn to it from a tent I have also condensation issues. In addition to the photos/vids, primarily from Franco, I made quite a number of my own to show the size and space. My unique needs won't be like yours probably but hopefully it gives you more of a view of what one is like so aid your consideration of the options.
As its recommended

As its not recommended (condensation issues) but showing what's possible

So far, I've only garden pitched to learn how and what I need to customize before real usage, so I can't talk from experience but I've learned a few things so far
– the optional poles are not stiff, I know Easton make stiffer ones but these aren't the ones TT provide.
– pole stiffness is absolutely crucial in the lower-flysheet mode as the more downward forward makes the poles bend so much they sway a fair bit
– recommend using trekking poles for strength, but you can get away with the optional poles with flysheet in upper recommended orientation if its not windy
– long narrow inside area but can be made fairly wide. I'm happy with the internal space.

– if you try to really seal-up (not recommended due to condensation) the side walls become quite vertical, you can see the angles in the above videos, so I've found with trekking poles basically the pegs are wanting to come out. Recommend getting Henry to fit guy attachments, I added later

and then using some stiff guy like Dyneema to help keep the load off the vestibule peg. I've fitted the guy attachments myself, I just got some Dyneema but I don't have any pegs here to try out the combination of additional pegs yet. I might additionally inside the fly make some guys up to peg towards the head/foot end to help take some load off the supplied external pegging points, but not played with that idea much.
– 4 pegs most of the time, plenty strong for most situations
– fast pitch. I can do it in 3mins but sure as I learn the right tension to put in the 4 pegs, I can do it in 2mins-ish with practice.
– the partially solid option I can testify really warms the shelter, we get 20mph off-ocean cold winds in my garden, when its bitterly cold for t-shirt but inside the Notch it is warm.
– I'm making a Tyvek footprint too, I'm just getting into MYOG.
Overall, if you're really seeking to minimize condensation, then the Notch in the high-fly mode seems a happier shelter, less of the peg-pulling mode and better tolerating lightweight poles, but you can lock it down if you need with additional guys and using stiffer poles, so useful if a good-weather trip has surprising bad weather. That's mostly my personal need, I tend to aim to camp when its forecast good but nice to know if I'm surprised by bad weather I can do that with the Notch.
I might get another TT for when its planned to be bad weather, I love bad weather but the travel to it usually blocks me, I'm a bike-tourer mainly recent years and usually if its wet+windy I can't safely bike to campsite. Might get a Scarp, not sure.
I absolutely love the Notch's weight / space ratios.
I got some Black Diamond Distance FL trekking poles I just happen to have a body height which is the range for these poles fitting the range the Notch needs, which are FYI 105cm is the absolutely lowest pole setting, and about 115cm upper but my poles go to 125cm to pull any sag out of SilNylon when wet from inside.
I picked TT because its clearly designed by an experienced intelligent shelter designer with good customer interaction, I'm sure if I have any genuine issue they'll get resolved with TT. I forgot when I ordered to request the guy attachments but we emailed and I got them delivered quickly with instructions, so good customer service for sure.
