> well, the -T makes it pretyt easy to grep for the bigger time hogs

Except the time at the front is the relative time since the start of the previous syscall. To find syscalls that take a long time, you need to grep on the time shown at the /end/ of the line.

Both are useful, but time /between/ syscalls points to times where the process is doing a lot in userspace.
