There are two answers that are the same in the first question of the poll and I imagine that I'd be picking one of the two: the one stating that I have more than one and that I like them all.
I have all ancestor Tamagotchis except for the Santaclautch (I am planning on getting one someday) and Yasashii (not sure if I'm going to get this one). They will always have a special place in my heart because I was a '90s gal and I grew up with them, but I have branched out in recent years. Those are my answers to your poll.
Different strokes for different folks, I guess. I can't speak for others who enjoy the vintage Tamagotchis but for me, they're the ones that started it all and there's a simplicity about them that can't be matched. Also, the Angel isn't the only one that's out there. There's something out there for everyone if you're talking about the vintage Tamagotchis in general. Though the Angelgotch is adorable, it's pretty low-maintenance when compared to others out there. Again, it depends on the person, but the low-maintenance deal with the Angel could be an enjoyable thing, or not. Each vintage Tamagotchi has a set of different characters, others have a motion sensor, and yet others might have a certain theme (like ocean, forest, Christmas, etc.).
I was kind of like you, except in the opposite manner. I couldn't quite figure out what the hype was about all the Connection versions. I even tried playing with one when I got back into Tamagotchis. Didn't like it much. I gave it another shot a few years later and now I'm collecting more and more Connections and enjoying them too. The more I read about the versions I don't yet have, the more I know about them and the more chances I have of liking them. The Connections are not my favorites, but I do enjoy the different features they have. The same could possibly be said in your case. If you have a chance, give your Angel another shot. You may be surprised.
By the way, none of the vintage Tamagotchis can get married or have kids. As for the bat, one of the cool things about the Angel is that it's equipped with a motion sensor. You can tap the side of the unit to scare away the bat. Features like this were pretty cutting-edge for a virtual pet back in the day, which is probably one of the other reasons why people get so excited over vintage Tamagotchis.
