The warranty is a valid point.
The LTT screwdriver has very small gearing which means that it is fantastic in a lot of iffy situations. It's honestly just a damn good screwdriver. As I said it's the best I've ever owned. LTT can go rot in a box, but as much as I despise the company, I am not willing to lie and say that the screwdriver is a bad or mediocre product.
It is compatible with standard bits. Standard bits work just fine in it. However if you want to store standard bits in the handle then you will only be able to store six instead of 12. That's the only real difference.
As far as availability of short bits, I did a good bit of research on it and found that you can order bit sets for low profile ratchets that are 19 mm. So basically all that to say that getting short bits as replacements is not difficult.
For what it's worth, I have used the nice snap-on screwdriver, it's honestly nowhere near as good. Of course this is just my opinion, but I'm being honest.
All that said, fuck Linus and fuck LTT.
