We pretty much tape everything when the trim is not being painted (we cut-in the ceiling, as pictured).
The results (razor sharp, straight lines) justify the time spent taping.
Rolling a room is faster when it is taped- the time spent taping is made up by the time you get to the second coat.
A couple things that we do, specifically:
-use green Frog tape 1.4"
-are very careful to create "perfect" straight lines (with tape) and sharp corners.
-press down tape with a putty knife, so paint does not get under it and marr the crisp lines.
-do not load the roller when rolling against the tape. less is more.
- the first coat can dry, as long as the above is followed, and you pull the tape immediately after the second coat.
-if paint starts to peel, then you will need to score the tape/trim edge with a utility knife.

can tape a room like this in about an hour, maybe less.
