You pay your money, you take your choice.
PCB tools mostly are preferential, be it picked up as a hobbyist or introduced it via work, I wouldn't go back to DT just because I am used to other tools (Altium and KiCAD), if I were to go back to Eagle it'd have to be V7 before Autodesk messed it up, as the "new features" are really not worth (for me) the pure amount of crap they have injected into it since.
I would always recommend trying EAGLE, DipTrace and KiCAD to anyone though as despite what YOU think, others might get on better with a n other package.
Yes it is frustrating when simple things are missing like as the mentioned dashed/dotted line feature, but you have 2 choices, live with that limitation or use a different tool. And just hope that it gets added in the future.
Say what you want about DT/EAGLE/KICAD the truth is they can all perform mostly the same functions as each other, it's just what you find easier to use and what you are willing to pay or not pay for.
I went with KiCad because of limitations in Eagle and DT, that KiCAD had at the time, yes they have since been implemented but that was my reason at the time to drop them, and when you spend a decent amount of time learning a new tool you kind of stick to it, I have EAGLE 7 installed for legacy, removed DT a long time ago, nobody in the hobbyist community I have seen uses it for OSHW projects, so I had no need for it.
