This just makes me feel really lucky. 
I have had NO problems with my Zelda on the Wii U. No lagging, no freezing, no closing down.
Same here with our Switch versions. Not lagging. Not freezing. No sudden errors closing down.
In all seriousness, while I agree it is a great idea to wait for problems to be weeded out and for Nintendo to patch and fix whatever, I feel there is a very vocal minority trying hard to convince the switch is so buggy it shouldn't be out. I don't see how suddenly it shocks people that this is meant to be handled with care. People that received a defective piece should be able to get it replaced.
In any case, of the 12 minutes I saw among some fair causes such as the console screen not working, weird noises and stuff a lot of nit-piking.
- With the grips, if you put them backwards then they get stuck. That is more of people not following instructions and then trying brute force and crying because that backfires on them. The same video shows a girl releasing them effortlessly with a screwdriver so it is not the 'stuck forever' people are trying to scare you into.
- The weak signal was a beta problem AFAIK fixed with the day one update.
- One of the guys complaining about the scratches on the screen takes the console out of the grip by holding the side instead of as directed. What do you expect?
- Complaining about the console not charging while on being tabletop are just complaining for the sake of complaining. You can charge it on the TV or by holding it with the controls attached, so only one in three modes can't be charged while playing at same time, which is a luxury. The console battery lasts heaps when in sleep mode so you can charge it before bringing it. I bet you it is a matter of time we'll get cradle to hold it while charging, but I bet that very same people will cry "hidden costs".
Breath of the Wild was made for the Wii U, not the Switch. Remember that it was ported to work on the Switch within the last 6 months.
Wii TP was shitty compared to GC TP, just remember that.
I'd argue that it was ported to the Switch with more than the last 6 months but that doesn't changes your initial point. I am happy Nintendo made sure to release it for Wii U instead of just switching all the work over to the Switch.
As for the comparison between TP Gamecube and Wii. I can't talk. I owned the wii version and its served me well, I have no clue what made it shitty since it was the same game, just mirrored and with different controllers.
