Opinions are all over the map on hingeless pages. Personally, I absolutely loathe split-back mounts. More stamps have been ruined by those types of mounts than any other, with the exception of those evil envelope-enclosure mounts from the 1960s-70s, where over the course of time every stamp becomes hermetically sealed in its own little tomb.
But I digress...
For my hingeless albums, I prefer the approach from Lindner and SAFE that use a 2-part page rather than individual mounts attached to the printed page. There's a printed paper sheet, and then there is a separate plastic sheet with rows that match the printed layout. There's frequently extra area on the perhiphery as the rows go across the whole page. This allows extra stamps or oversized items to be placed on the page.
This model also allows you to (1) view the back of the stamp without removing it from the "mount" which is very handy when checking either for expertization marks or NH/LH status, and (2) easily write in pencil on the printed page without disturbing any of the stamps.
Also, you can buy blank hingeless pages in various row height and number configurations to place in your albums for additional varieties.
It makes for a very homogenous presentation.
They're not the cheapest hingeless pages in the world, but I swear by them. The only time I've bought others (Palo, Davo) are when SAFE or Lindner don't offer pages for that country or era.
Note: The plastic used in the sheets is VERY robust, much heavier than normal mounts, so your stamps are much better protected, but also results in very heavy albums.
P.S. With the "mounts" effectively being one large sheet, individual stamps are far less likely to shift or fall out than with the traditional open-top hingeless format where every stamp is in its own individual mount.
Here are some pictures of both preprinted and generic pages (not mine; gleefully stolen from an
ebay listing). Some of them show the backs of the stamps and you can see how easy it is to view the backs simply by pulling back the plastic sheet.
