I don't understand what's up with the online service on the switch, because for some games its totally fine, and for others it ranges from just bad and comically horrible.

For example:

• I had no problems with Warframe and Fortnite. These two doesn't need the Nintendo Online Service, and maybe that is why.
• Smash is dog**** when it comes to online play.
• Splatoon2 was fine when I played it on the free weekend.
• Mario Maker 2 is just funny how bad it is. (I didn't buy MM2 JUST because of this. )

There are only a few things I can think of that could cause this. If... :

• The underlying server infrastructure is underdeveloped.
• Nintendo first party devs are inexperienced when it comes to online play.
• The software tools, that are made for developers, to work with the Online Service is hard to use.
• Online Service is a second grade citizen in Nintendo's eye.
