I ended up looking at two fermenters. The Brewbuilt X3 which is loaded with a lot of features in the base package and the BrewTools MiniUni+. Both in the ~7 gallon range and both are jacketed fermenters.

Huge difference in base prices. About $1100 vs. $349. I was pretty excited about the BrewTools based on the price alone, though I eventually went with the Brewbuilt conical. If I wanted to go up to the BrewTools ~10 gallon, I could get 2 for the price of one BrewBuilt, though that doesn't really work for my typical batch sizing.
The BrewTools MiniUni has a 2" TC port on the bottom but it is useless when on its included base. To make use of that bottom port you have to either add the optional leg kit (~$35) or hang it on a wall with the included hanger. Unfortunately, I don't have a dedicated spot that I can hang it that will work for me. If I had a truly dedicated space where I can have water and drainage where I needed it, this would be a very attractive solution.
For the BrewTools, adding the legs, I need a 2" TC butterfly valve, 2" 90 degree adaptor, gaskets and clamps to get that dump port horizontal below the stand and just barely above the ground unless its up on a table with a hole to come straight down. The BrewBuilt has a 3" TC port, butterfly valve, gaskets, TC clamp, as well as a bottom dump chamber. You'd have to add the dump chamber to the BrewTools and the horizontal alignment will get messy when you disconnect the clamps.
I want to do O2 free transfers to kegs. I need to add the pressure kit ($179) to the BrewTools. The BrewBuilt includes a pressure kit. Now the BrewTools pressure kit includes a spunding valve, which BrewBuilt doesn't have on theirs. But A Kegland Blowtie spunding kit is only $26 to add to the BrewBuilt.
Front 1.5" TC ports. BrewTools has 2 and BrewBuilt has 3... But its a jacketed fermenter and if using a chiller, you will use up one of those with a thermowell for temp sensing... so you lose one off of each.
Taking samples or racking. BrewBuilt includes a sample port that you can use on one of those 3 front ports. That is extra on the other (~$30) plus gasket and clamp. Granted, you can use the pressure pack to get liquid out, but that isn't necessarily useful during fermentation if you aren't building pressure and you have to inject CO2 to push the liquid out.
TOSNA additions. The BrewTools has a single 4" TC port at the top. You either take the 4" plate with airlock off to add nutrients or you leave the optional pressure pack on and remove its single centered TC opening to add nutrients... which isn't really a bad deal if you have the pressure pack. The Brewbuily has 2 TC ports on the main conical and another two on the top 8" TC plus another on its pressure kit. Plenty of options for nutrient adds.
Moving the fermenter around. While neither probably should be moved when full, sometimes things don't work out as you want. The BrewBuilt has the option for caster on legs that are slanted outward for stability. Nothing at all the same for the BrewTools. The BrewTools will use less floor space, but it is really built to be in a stationary spot, preferably mounted on a wall.
Jacket coverage. The BrewTools is the big winner here. The BrewBuilt has no jacket on the conical portion while almost all of the BrewBuilt is jacketed. That will certainly translate to $ when it comes to chiller electricity and cooling time.
If I had the space to wall mount one of these BrewTools units, I would have gone with that instead as it would be great for mead. I just really value the potential to roll it around for cleaning or just go get it out of the way while it is full.
I will add that for still meads the BrewTools would likely be a great choice with the addition of a racking arm and if it was up on a table for a gravity transfer to work. If you are OK with some CO2 and a pressure kit, both will do what you need. The BrewTools would also be great as a second temp controlled fermenter/bright tank... but I think it really needs to be up on a higher table top or wall mounted if you want that option of gravity transfer or to be able to get a bucket under the dump port.
There are more items to consider but for myself, to get the BrewTools similar to what I wanted it ended up having a lot of add on accessories that brought it fairly close to the BrewBuilt. The BrewBuilt was less expensive kitted out, though less expansion easily available and I didn't have a good option for moving it unlessI bolted the stand to a rolling table. A higher center of gravity doing that wasn't something I really wanted to do.
I'll add temperature control in another month or three.
I imagine that I'll edit this tomorrow after another read through and add some more thoughts.
