garmin venu problems

I am seriously thinking of selling the Garmin Venu
I come from a Samsung Active 2 and the truth is that garmin I see several shortcomings that I will list.
1) You cannot enlarge the  notifications fonts.
2) It does not give me hydration alerts, even if I configure it.
3) Comparing heart rate readings I see no difference with samsung.
4) I like the measurement of oxygen saturation but it is unusable because the battery consumes it very fast.
5) Third-party watchfaces take 3 seconds to show up when you turn the wrist

I would like to know your opinion and if anyone had the 2 watches
