Depends. If you intend to show results that could be referenced by a hard link that the user may share (such as search results or blog entries), then pagination is better. Transactions (like bank statements) or lists of lots of similar looking data are better suited for infinite scroll. If you aiming for performance, it depends on how much data you need to request and if you can shunt or lazy load the data.
