The four basic types, apex:pageBlockTable, apex:dataTable, apex:dataList, and apex:repeat are all basically the same thing, but present different renderings.
apex:pageBlockTable represents a table formatted and styled to look like a related list table.
apex:dataTable is an unstyled table suitable for use anywhere outside of a apex:pageBlock (but may be used within one).
apex:dataList renders a ul or ol element (unordered or ordered list, respectively), with li (list item) elements comprising the rows.
apex:repeat allows any arbitrary output based on a template. The four elements require value and var attributes, iterate over a collection of some sort, may generally be nested inside each other, and are limited to 1,000/10,000 rows of output, depending on the apex:page's readOnly attribute.
Edit: As pointed out in the comment, the main difference with apex:pageBlockTable, compared to the other three, is it must appear in a apex:pageBlock or apex:pageBlockSection, while the other types can be rendered anywhere that Visualforce is allowed. There's a very specific limitation about apex:pageBlock not being available in email templates, as well, so you'd naturally have to use one of the other three types of iterators.

An ordered or unordered list of values that is defined by iterating over a set of data. The body of the <apex:dataList>component specifies how a single item should appear in the list. The data set can include up to 1,000 items
<!-- Page: --> <apex:page controller="dataListCon"> <apex:dataList value="{!accounts}" var="account"> <apex:outputText value="{!account.Name}"/> </apex:dataList> </apex:page> /*** Controller: ***/ public class dataListCon { List<Account> accounts; public List<Account> getAccounts() { if(accounts == null) accounts = [SELECT Name FROM Account LIMIT 10]; return accounts; } }The four basic types, apex:pageBlockTable, apex:dataTable, apex:dataList, and apex:repeat are all basically the same thing, but present different renderings.
