Just to add to Mike's input - the proto boards require the use of wire-wrapping techniques (of which I have none) or lots of little solder/wire bridges to connect things together.  If you are good at wire-wrapping or have a simple design already laid out, the the basic prototyping board is a good, inexpensive approach.  OTOH, Mike's SuperProto board is powerful enough for all but the most hardcore interface projects.  The 6522 is a fantastic I/O chip (probably why the Apple III and the early Macs had so many on their MB's) and the inclusion of EEPROM is really convenient.  I added switches so I could select different EEPROM images without having to re-burn them.

I've used both, and they each have their place with prototyping.  I used the basic prototyping board for Apple II Pie due to space and location requirements (and being a simple design).  I used the SuperProto board to Synthesize an SPI interface to an Arduino Ethernet Shield.  I would use the SuperProto board any time I needed to, in Mike's words, save some time and hassle.
