The advantage browser-based ones have is it’s generally easy to copy/paste any text you need. I used one that ran as its own desktop software and made many of the key text fields uneditable, instead of letting you copy text from them but refusing to save any changes to those fields that must not change. Want to grab the order number for this customer? Too bad! Type it yourself or export it to PDF and copy it from there! I was so happy when I discovered a little program that lets you copy any text on the screen by effectively taking a screenshot, running OCR on the screenshot, and putting the output onto your clipboard. Still took more effort than simply right-clicking the text and hitting copy, though, or double-clicking and hitting Ctrl-C.
