I built Timothy's design years ago and it is absolutely amazing, it became my primary workbench and I use it every day since I built it.
The features that made the MFTC stand out for day to day work are
1. the drawers with your most used tools. I included a Sys-4 TL / Sort 3 with all my frequently required hand and measuring tools in the top shelf and
2. the tool shelve - this feature is by far the most genius thing about it and seriously lacking on the MW 1000. I always got my track saw, domino, palm router and sander within reach. That completely changed my workflow, saves a lot of time and keeps stuff organized.
3. the height matches any Festool worktop height of 900mm and I often times use it as an extension
4. vertical clamping all around
5. a custom made hose and cable holder I can attach anywhere to the clamping channel.
The one advantage of the MW 1000 however is the optional extension table as it can also be used as an extension on e.g. the MFT, Kapex, CS50/70, CMS, etc. Also the attachment of the optional MFTC extension tables can be a bit fiddly; not a biggy if it's not an everyday thing for you though. I think with a bit of adjustment to Timothy's original design you could probably pair the MW 1000 extension with the MFTC quite easily.
Surprisingly the empty weights of the MFTC and the MW 1000 are more or less on par at around 26kg (depending on how you build it). That being said you will not drag it either upstairs without unloading; more than 2 or 3 steps are out of the question. The 8" tires are generally enough (use solid ones for sure, no air tires! They'll bounce if you work with a hammer and pressure differences might require frequent adjustment of the other legs!).
The entire trick that allows the MFTC to be pulled up stairs are the sliders on the front side btw. You need to carefully design and mount them in a way that their apex coincides with the outermost tangent of the wheels and ensure you mount / make them long enough for common riser heights. If you mess that up the wheels will always get stuck under the treads / nosing.
If you regularly have to tackle stairs I'd take a serious look at the Bora Centipede. Setting up (including the worktop) takes less than 20 seconds (you can use a MDF slab, 2x4's or a Paulk style bench), you can carry it in its pouch like a backpack, and it uses hardly any space or weight. It is self leveling and the more weight you put on it the sturdier it gets, with anything over 70kg of weight on it you can even use a handplane on it (I've loaded it with half a metric ton of dry wall sheets no problem).
