Wireless scanning is so much slower that I consider it a worthless feature for most offices

The Epson DS-320 has an ingenious feature for scanning plastic cards that takes the card in from the front, rather than through the document feeder, scans it, and then ejects the card back out the front

Both are similar in size, and both accomplish the same major features, except the Brother also supports wireless connectivity over a network (so no USB required, although I choose to use USB because scanners seem to have enough hiccups without introducing the wireless network as a variable in the equation of scanning success).

If you can get past the size and weight, though, the scanner does offer some very handy features that are not typical of a mobile scanner

The technical features are enough to please a rising artist - likely not enough for someone who is looking for extremely detailed scans
