Everything in life goes in a cycle. Many years ago, document scanners were the hot thing to have. Then they became integrated into all-in-one printers and the stand-alone scanner became a bit of a dinosaur. Now, everything that is old is new again and stand-alone scanners are hot. You see them in just about every doctor's office - the receptionist scans your license and insurance card along with the other paperwork for your visit. My accountant scans all our tax receipts and W-2's, etc. when we come to see him each year. Personally, I have an AIO printer at home and a portable page scanner as well.
Which one is best really depends on your type of business and what you're using it for. If you are a salesperson on the road a lot, the portable scanners can be really handy.
They're great for scanning samples of something your client shows you or scanning documents that you can't take with you. If you scan multi-page client files, the sheet-fed ones are probably what you want.
