The first bitcoin wallet was bitcoin core, created by satoshi.

The most used are probably electrum (very good one) and blockchain.com(bad one)

I don't know buxtank and I would stay away.

Xapo is not the best wallet, but it has good reviews.

^ It is a Bitcoin-Qt wallet or known as Bitcoin Core wallet and thanks to Gavin Andresen he called in that way.
I know Xapo but I dunno Buxtank, if that is not an open-source wallet, please stay away because that is not a safe wallet. Nevertheless, with a free wallet Electrum, even though this is a safe wallet but be careful because this is also a buggy wallet and should up with the date of the latest version. Try a Hardware wallet though.
