Edit: I'm. Fuming. At my mouth. I made a very, VERY comprehensible reply to this, but it's the third time when I post something on TT it posts blank with no way of getting it back.
Alright........ Ekhm.
You have to specify which "anniversary 2017" model you mean.
-is it the mini? Don't bother, it's none of the things you described, whatsoever, it's just a keychain.
-is it the Japanese release of P1/P2's? Angel is more exciting than a normal P1/P2 but has the same core principle. I'd stay with Angel instead of getting one of these, besides getting an actual vintage one isn't super expensive.
-Is it either one of the two 20th anniversary mixes? They're the color versions, mind you, so if you're a vintage lover then perhaps that's not for you, though they are based around references of vintage tamagotchis. As a version they do fit your description fairly well, compared to other color tamagotchis. Gift ver is barely different from the first version of it, it just has a few extra minor features and 2 different characters.
I'd say go for either the Angel or maybe one of the Anniversary M!xes.
