Since this old topic has returned, I figure I might as well say what DOS's I use today. I probably voted for SpartaDOS in this poll years ago, but if there was more than one choice (I can't tell anymore as it just says I already voted) I probably would have selected MyDOS or SuperDOS as an alternate back then.
Today, I'm sticking with the two main DOS's, shown by the poll, SpartaDOS X and MyDOS. I Have the MyIDE 2, which is made for MyDOS under it's MyBIOS, but FJC and others (SpartaDOS project?) have made the tools to use MyIDE 2 with SpartaDOS X also now, essentially making the MyIDE 2 work like a SiDE 2. So I have a CF card for both, since there are certain apps and desktops that work with one or the other DOS, but not both. So depending on what I want to do on my Atari, I either Boot with MyBIOS and MyDOS or with an OS of my choice on my 32-in-1 OS and SpartaDOS X. If I could have everything working with either DOS, then I would be 100% a SparatDOS X user for all it's power.
I have been meaning for years to look into Atari DOS 4.0 seriously, from the little I know, it seems powerful and user-friendly and might have become the standard for all XL/XE's had it ever been officially released. But switching to it today would depend on compatibility, and with everything being basically DOS 2.5/MyDOS or SpartaDOS compatible, who knows. Also, if 4.0 is HD and large capacity ready or not...probably not.
