To be honest, the main reason I got the Q Marshal is because I love Fossil watches and I was about to by the Q Founder when the salesman at the Fossil store told me that the new ones were coming out at the same price and were supposed to be an improvement over the current models, so I decided to wait. But to compare notes:
1. I agree that the vibration isn't what I would like either. I have my phone with me so know something has come through, so this isn't really an issue for me.
2. I haven't had any trouble with the charging puck, it usually takes a second for the watch to start charging but it always does. I do prefer the chargering cradle that my S2 Classic uses, seems to have a better contact and secure hold. My complaint about the Fossil charger is that $300.00 for the watch and they can't put in a charging block? Only the cable? Fortunately I have a couple of extras laying around.
3. I haven't experienced any random disconnects that I'm aware of. If I walk away from my phone far enough it'll disconnect but reconnect as soon as I'm back in range. The only thing similiar to this is that sometimes my phone notification sounds will stop working and the only way to fix that is to resart the phone. This has only happened when connected to the Q Marshal, it never happened with the S2 and doesn't happen constantly, just on ocassion.
4. I haven't really done any drain times as you have but I get more than a full day out of a charge. I take it off of the charger around 7 am and put it back on around 7-8 pm and I'm generally around 40-45% left. I get text messages and emails all day so my notifactions are pretty heavy, I'm happy with the battery life so far. I have downloaded a couple of watch faces but still use a preloaded one, I just like the look of it.
All in all, I'm very satisfied with it. I am also very satisfied with my Samsung Gear S2 Classic. The Os's are very different and has taken some adjusting to get used to the diffences between Android Wear and Tizen (the Gear OS).
I do like the size of the Fossil watch face itself better but the clarity is not as good as the S2, also the S2 doesn't have the "flat tire", the sensor is in the center of the face, but the "flat tire" doesn't bother me at all, I don't even notice it any more. As I stated in a previous post, there are pros and cons with both and both are very nice watches.
