It sounds like you mostly want a smartwatch for notifications, but you also want it to keep you entertained? Perhaps there is an app opportunity here for witty reminders?
I had a Casio calculator watch back in the 1980's. It had this number invaders game that was inspired by the arcade classic Space Invaders. The number version on the watch was good for a few minutes of entertainment while I was waiting for a ride home from school, but it was no Atari gaming console.
Eventually I got bored with the calculator watch after the novelty wore off. It was still useful, so I kept wearing it... at least until I got old enough to realize it was a girl repellent.
You don't say why you got bored. I would think that it would be more important for the watch to be useful than exciting, but why would a Samsung, or any other smartwatch, be more exciting or fun? I suppose there are third party watch faces for other platforms that might keep things fresh, but I think most people end up sticking to the same faces most of the time. There are more combinations for Apple Watch faces than I ever get around to using.
Between the sheer number of available apps, existing watch faces, watch face complications, ease of switching between the multitude of bands available from Apple and others, I'm not sure how a smartwatch could be much more entertaining. I think the truth is that any smartwatch is going to be limited when it comes to the entertainment factor. It's not a gaming or entertainment platform in the way an iPhone or iPad can be. It's a fitness tracker, notification tool, and an extension of your iPhone. You can only play with it for so long.
I do not find my Apple Watch to be boring or entertaining. I find it attractive, convenient, and useful. After two years of wearing it, I actually like it more now than I did when I bought it. I have never been able to say that about any devices I have owned for two plus years.
I can't say whether you will like it more or not the second time around, but I wouldn't expect it to be any less boring... unless the upcoming Siri watch face offers a more dynamic face that you might like.
