For me, stays are better, as almost all my travel now is personal. This year I might get close on nights, but I don't have 50 nights of vacation time
I top off what I need doing mattress runs to inexpensive properties as I find them during the year.
The bloggers are probably referring to stays being easier/cheaper because if you live near an inexpensive Hyatt, it IS easier to just hop in for 1 night during the weekend, or just go there to check in, leave and go about your business.
It really is a matter of your travel patterns and how likely/easy it is to get there with stays or nights.
