I plan to start building my 56th model in a couple of days time, and although five or so of my most recent planes have been ARTF's, building from either kits or plans still appeals to me enormously (No 57 will be plan-built). I also enjoy occasionally "growing" them on my board too, with no plans to guide me (although the flight characteristics of some of these models have been, well, not good!). But I really enjoy building - especially when the end-result is unusual, or when it flies really well
For me buying an ARTF model isn't a matter of having no time to build. I tend to buy them when I go to a show and see something appealing which, when I examine it, I then think is built better and lighter than I could build for myself. Then there's the "other" reason - when I've had a run of crashes, the weather is great, and I just want to get something in the air again - but quickly!
Anyway, all my current models have now had their Winter maintenance, the building board has been dusted-off, and everything's to hand, so I'm looking forward to getting-to-grips with the Mojo kit I imported from The States late last year as my Winter project - yep, it's been a busy Winter for me
