I couldn't really answer properly, as there is really not a'primarily' for me, because....
I have always been an admirer of an 'all-around' horse; when I showed APHA and PtHA after I 'began' in registered horses with QH's, in the mid-fifties-that's always what I wanted...a horse that had the mind, conformation, and athletic ability to 'do it all." I felt the same way about my minis; wanted an 'all around' horse. To that end, with minimal ability to travel and show, I 'made' two AMHA Champions,both geldings, also w/ numerous ROMs between them, and a Top Ten Honor Roll for ME, in the category of Showmanship, along the way--all this w/limited ability to travel widely or often.
I trained all of the horses I've shown in breed shows, WHOLLY;also bred several of them, though I no longer breed. I especially liked to 'create' horses for Driving, including Roadster, and a personal favorite, Obstacle Driving.We also did Showmanship and Hunter(though I was good at it, I don't really 'love' Showmanship--it has became too 'stilted' for my taste.I've never cared a lot for Halter,though I did show there with success; nor was I much interested in 'fluff' classes like Liberty.(FWIW, I felt the same about ridden 'Equitation' classes(became increasingly stilted, 'fakey', IMO); always felt it was a better 'test' of horsemanship if you stayed well with a good cutting horse(I've ridden both 'inside' and 'outside, real-world' cutters), or sat deep and didn't interfere with, a good horse or mule, coming straight UP, or straight DOWN, a steep rugged mountain, rounding up goats; or running a good, CONTOLLED, barrel pattern, or having a good goat tying run, for that matter--just for a few examples!)
I'll just say I 'had my fill' of the breed ring, so don't show there any more. I am very interested in CDE, and its 'principles', though will likely never be a 'genuine' competitor...there are none anywhere near me, and I am just not really able to be gone for days nowadays, for several reasons. I enjoy the occasional clinic on the subject, though, and like to practice the principles and procedures!I also enjoy trail driving, and the occasional parade, often complete w/ 'homesteader' outfit with my pair or a single!
Of my 6 minis, 5 drive(one is green, but has been hitched and driven lightly); the 6th is a 'small'-30.25"- who satisfies my 'need' for a 'cute pet'and nursing home visitor(a practice I 'pioneered' in my area.) On top of that, though, this nice little mare is of quality conformation, has my favorite bloodlines,and would undoubtedly be an excellent broodmare prospect for producing quality 'smalls'- so,the best of all worlds!
