Update:
I tried 3 different mats. The husky mat (for 2015-2021) and two Maxliner/smartliners. One was for 2015-2019 Transit and the other for 2020-2023.
I liked the look and feel of the Husky mat better (was also the cheapest - reduced price) but the other two have better coverage of the floor, however, the main miss was the fact that it was for carpet only with little spikes on the bottom.
The product was not clearly described on that famous marketplace website we all know. ;-)
So, surprisingly I chose to stick with the 2015-2019 Transit Smartliner and not the most recent 2020-2023 one.
The most recent version fits perfectly especially under the center console but just about everywhere else it's cropped a little compared to the older model. The older one covers more.
The areas that I cared about more was the driver's side under the left foot - less coverage - under both feet actually, and near the ledge facing the doors. The older model goes even over the edge while the newer stops just before. To me it's better to have it covered for cleaner sweeping towards the exterior and also if there is a big spill - if the liquid can't be contained in the mat it will just flow towards the door and outside - unlikely under the mat.
(Such a feature saved my Honda once when I spilled 5 gallons of water from my solar shower bag - pretty much everything poured out of the car through the passenger door while the carpet stayed dry. (it was Weathertech))
The 2015-2019 Smartliner model also has a little extra kick towards the back of the van between the seats and also climbs to cover a little bit of the wheel wells close to the doors which all the other liners don't.
Some photos below.
Center console:

Smartliner 2020-2023:
(looks best, perfect fit)
Smartliner 2015-2019
(doesn't fit as well, but better than Husky, and has some extra between the seats)
Under the driver's feet:
Husky 2015-2021
(this one has the best coverage under the left foot)
Smartliner 2020-2023:
(little short there and probably where your left toes will sit crap will fall behind the mat)
Smartliner 2015-2019
(a little better coverage under the left foot)
Ledge at the doors:
Husky 2015-2021:
(don't have a photo but it's similar to 2020-2023 Smartliner, and you can also see it on the faroutride site)
Smartliner 2020-2023:
(mat stops just before the edge, though still better than the Ford OEM mat that is cropped even more)
Smartliner 2015-2019:
(covers the ledge and also some of the wheel well bulge which I noticed first on
@Bazz99 photo - so thank you for that)
So, to summarize I went for what I thought was the most practical full coverage with just a little compromise on the perfect fit aesthetics under the center console.
I hope this helps.
