Felo's contoured "woodie" handle is the best screwdriver handle I have used, and the shafts are commensurately excellent.
Felo woodies have an image problem: they are sold too cheaply to be broadly viewed as a "super premium" product comparable to or better than PB Swiss or the US white van brands, even though they're well made with handles of real materials (wood, leather) rather than petrochemical concoctions. If Felo asked PB Swiss/Snapon prices, and you'd see a hordes of people proclaiming them the greatest screwdrivers ever. They're cheap so people don't, even though it would not be inaccurate. From a design and quality perspective, they are good enough to be stocked for years by fancy fashion/home-goods chains such as Germany's Manufactum.

There is also a practical problem with Felo woodies: too few options. Felo only offers slotted, PH, and PZ woodies. No square/hex/torx, let alone oddities. For PH/PZ they are my choice. (PB Swiss slotted is my choice because I prefer their tip shape.)
While I think the woodie screwdrivers are Felo's best tools, their bits are also as good as any. (In hex I prefer Wera hex plus.)
Their 1/4" drive set is also fantastic, especially if you need both AF and metric. The ratchet has a top tier handle, though the 72T mechanism is barely better than Snapon/Bahco or other such mediocrities.
Likewise, I like Felo's"Bit Boy" bit holding handle. Very comfortable in the hand and versatile to stash somewhere. Felo's bit ratchet is also one of the better ones. Reverse Gear's locking flex bit ratchet (sold with minor variations by Facom/USAG/KS Tool/Würth/Deen/Mac/Toptul/likely others) is currently my most used because of its versatility, but Felo is more finely crafted, I prefer Felo to Wera (fixed Reverse Gear), Wiha, Stahlwille, and any others not named above that have gone through my hands. Koken I don't compare because it is so much larger than the others.
However, I am unimpressed with Felo's "Smart" nutdriver set. It is expensive, and the shaft retention on the handle is not very secure.
Where did you bought them and what's the price? I see that Wurth is selling them under their name.
I've bought Felo from Manufactum, as well as more traditional tool sources such as KC Tool, Amazon, and Detroit Metalworking Supply.
Würth is actually a bit different, though unless you look at them next to each other that is very hard to determine. While the handle texture and give is similar, Würth's contour is almost a caricature of Felo's, with two exaggerated bulges but a less nipped waistline. For me at least Würth is less comfortable. Here's two direct A-B comparisons:

I don't know if it's simply Würth's current policy not to label COO on any tools regardless of origin, but it also bears noting that they do not say "Made in Germany" on them. Quality seems similarly excellent. I prefer Würth's spinner handle to Felo's because it has the female 1/4" square on top, though the perfect spinner handle would be Felo grip with Würth through-shaft, and Stahlwille QR square...
However, Heyco does sell Felo Ergonic screwdrivers in their distinctive green color. You can find them on Amazon, or at least could at one point. Heyco also carries options Felo does not offer themselves, such as this great little 2.5mm slotted terminal screwdriver.

Well, not since the 40's anyway . . .
Best price I've found on their wood handled drivers is here, they dropship from Bondhus.
Bondhus is Felo's US importer. And at that price everyone should try Felo woodies.
