I'd argue the layouts "inbetween" are much better. One being 75% (~84key) and the other one 90% (full-size that fits in a rack). The thing is, a lot of software depends on using arrows, the nav cluster (6key), sometimes the numpad (10key) or even the odd three keys above the standard nav cluster. Both these layouts have essentially all keys: 84key keyboards usually only miss a dedicated Insert (which is a pity IME), perhaps right-hand-side Super, and a dedicated Pause/ScrollLock; the 90% layout has everything and don't forget the tenkey can be used for navigation too with numlock off.
I obviously prefer split keyboards like my ErgoDox, but that's a completely different form factor, esp. with all these thumb keys. Embedding a tenkey into the staggered layout is easy too.
However, when I don't care about customization and adequate comfort, the "inbetween" layouts do the job alright. For example, when I have to configure some system from scratch or do something in plain Visual Studio, the function keys and arrows come handy.
