The most two heard about text types are probably Byzantine text and the Alexandrian text.
There are actually many text types, well more than two. So i really shouldnt say many text types.
Byzantine text type
Alexandrian text type
Caesarean text type
Western text type.
And… another one.
Yes the Syrian line is on its own, people often put the Syrian line of texts such as the Peshitta under the Byzantine text type but this really should be his own text type.
This page is mainly about the New Testament manuscript text types.
