Mine would have to be my v2 and morino and Id l I like how they are simple in that there is no worry about work, and school adm whatever, they are more pet like in that sense. There is just something about the morino that made me fall In love, (mind you I do love the vintages) and the v2 was my first tamagotchi that I remember well (a pink v1 was the actual first but it got lost.... I think it ran away when we moved).
I picked one of each, vintage, connection and a colour because comparing them is like comparing apples to oranges. They are very different things and should not be compared to each other it just doesn't make sense to
