I had some lovebirds, a parakeet (quaker), and some finches in my lifetime. The finches were cute and quiet. They are a bird that needs company so should be bought in pairs at least. However they are not very “intelligent” as far a bird species are concerned. I do not believe they are a conure.
Both lovebirds and parakeets are considered small-medium parrots so I believe they are conures. They are fun birds, you can hold them if trained right (which requires time and patience), and they are pretty smart. However they make awful sounds. If you are like me you think that you could get used to these sounds but let me tell you it is really quite difficult.
Which did I enjoy more of the conures? The lovebird or the parakeet? In all honesty I would say they were really similar birds, probably because they come from the same family. I would say either is a good bet. However parakeets have a dander that comes off of them that is a bit stinky and can be bothersome if you have allergies. On the flip side, the lovebirds squawk is a bit more bothersome than the parakeets.
Also please consider that if you have a dog or cat they may try to “get” your bird.
Having said that I really enjoy birds as pets, you just have to find the right “fit”.
