It's called brand-loyalty, right? You would probably be in love with the FS 4. My point is: You wouldn't even have tried other brands. Let me give you an example from my own experience:
I was craving for Specialized Turbo Levo Comp. Since I could not buy it (or even try it) in May last year, I started reading what other EBR members had to say about e-MTBs. PDoz is the EBR member who knows the most on electric mountain biking on these Fora. Browneye had created an "eMTB options for 2020" thread and he was describing his numerous visits to all possible brand stores down there in Orange County, demo riding e-MTBs from different brands. To surprise of everyone, Browneye went with a Giant Trance E+ Pro 2, and was delighted with both the price and the e-bike features (not forgetting about its looks). He bought the Giant e-bike because PDoz turned Browneye's attention to the brand and model.
All of that focused my attention on Giant Trance E+. I found the Trance E+ Pro 2 had excellent features, was beautiful, and far cheaper than the Levo; and it was available. Now, I have ridden Trance E+ for almost 2000 km and am still delighted. Actually, the only sub-standard feature of Giant e-MTBs is the dropper post that I needed to replace with a better product. But even stock tyres in Trance E+ were top-notch! Now, other EBR members have bought Giant e-MTBs, such as Fathom, Stance or Trance and are very happy.
I have told you the story to illustrate how valuable the EBR Forum is. I am personally thankful to so many respected EBR Forum members for educating me. I'm not the "I know the best what would be good for me" person anymore
