After 12 years of printing individual layouts (plus some photobooks of vacations), I finally switched to all photobooks in 2016. I stuck with individual prints for so long for 2 reasons. First, when my kids were younger and I wanted them to be able to look through the albums, I needed the durability of page protectors and the ability to re-print just one page if anything got damaged. Second, I don't scrap in chronological order but it would bug the heck out of me to have books out of order. In 2016 I decided I was going to make a real commitment to staying caught up so that I could print chronologically in books. I still don't necessarily scrap in order, but I pick a time period (say Jan-June 2016) and stick with it until the time period is 100% done and I can print the book.
My main reasons for switching were the bulk of albums and the polished appearance of the books. I'm saving money by printing as books, but it doesn't feel like it; spending a little at a time throughout the year on the albums and printing was easier budget-wise than 2 big payments each year for the photobooks. I printed through Shutterfly and did the upgraded layflat pages (whatever they call the option that has thicker paper as well as the layflat). Even though I could fit my year in 2 volumes, I'm going to spend the extra money next year to do 3 volumes instead. At 90-ish pages, the book is so thick that I'm a little worried about whether it will hold up over time. (Nothing against Shutterfly's quality--I'd have the same worry about a book this thick printed anyplace. So far so good, but we've only had it for a few months.)
ETA: Rereading your question, it seems like you're really trying to decide whether to keep your layouts only digital instead of printing. For me, it's worth the expense to print. No one would ever see the layouts if I didn't. My kids just aren't going to stand around a computer looking at digital layouts the way they will the printed books. I suppose I could try something like a digital frame, but digital just doesn't have the longevity and long term draw that print does, IMO. Then again, I'm lucky enough to be in a position that the cost for printing is an inconvenience but doesn't really take money from anything more important. If that wasn't the case, I would probably only print a selection of the most important layouts from each year (ie, my favorite photos, milestones, etc).
