If you ask me, if it can fly, you fly it.
There are advantages to trailering though. For example you can mobilise 24 / 7, day or night and in almost any weather! Also no flight plans required. Sea crossings are much less stressful too! and think of the component times you are saving on. Also if it breaks down you can recover it yourself! Probably take your own fuel too.
Flying long distance to a location just to do work makes it an expensive taxi.
