Given the astonishing level of accelerated development that computer science and technology has undergone over the past 32 years (MIDI first hit the scene in 1983) I think that DAWS are incredible tools, all of them, and we should get some perspective. It's not really what DAW you work in, it's what you do with it and how you do it.
All DAWs do three things: 1) record, edit and playback MIDI, 2) record, edit and playback audio and 3) handle plugins-- instrument and signal processing. That's about it. You can have the best DAW, the finest outboard gear, etc. and still make crappy music that has little nuance, depth, clarity, punch, power, groove, drive, beauty, sense of the sacred, sense of the ancient, sense of the cosmic, catchiness, dreaminess, heroic passages, contemplative passages, humor, originality, authenticity and/or the numerous other qualities and values that cause us to love music so much. There are no perfect tools because nothing humans make is perfect, as we ourselves are imperfect. The digital musical tools we have nowadays are incredible musical instruments. If one is always hoping for the next-best-thing-around-the-corner thinking that will help them make better music, I think that is a delusion. Better recordings? Maybe, depending upon the ears, talent and skills of the producer and engineer. But better music? That come from living better, from thinking better, from feeling better and from, I hate to say it, from the same source that honesty, truth, love, compassion and all good vibrations come from. Each person gets to decide what that source is and what it means to them.
I've had numerous composition and classical theory students who are computer engineers, both in software and hardware. They are usually excellent students, always curious, sincere, motivated and eager to learn. I cannot imagine how difficult and detailed writing a DAW must be. It's not just the number of lines of code, but the thought, creativity, design, planning, testing and decisions that went into it. And for what purpose? To serve music!! What a great way to use one's computer talents. If we could only get all the nuclear bomb programmers to change their roles and start making software to advance the arts, humanities and social justice, then maybe science and technology won't be in the hands of the dark forces that may screw it up for all of us.
The triplet issue may, or may not, ever be dealt with, I don't really know. I do know that when I am inspired and composing, it's a minor detail that has no impact on how I write. I too have been critical of Sonar's notational limits, but in some ways Sonar's notation editor is quite good, compared to the others, for example the design: letting the composer/orchestrator/arranger see the staves across nearly the entire screen is something I took for granted. It makes composing less about the tool and more about the ideas. Also, the scroll bar. Some notation editors don't have them, Sonar does and it is often the fastest way to get 100 measures forward or back. Both of these features really help those who work with a lot of instruments or write pieces longer than 2-3 minutes.
