Depends how you like your draw too...
The Nord and the breeze are quite different.
The wife loves her Nord, but it's way too airy for me.
I quite like the aspire spryte though - cheap coils that last well and are available almost anywhere, adjustable airflow, comfy form factor.
Then there's what it's for...
I like my odo pods because the whole thing is smaller than my finger, weighs nothing and the draw suits me quite well.
I couldn't see me having a requirement that something like a pal or potato would fill - it's not so small as to be unnoticeable (like the odo) so that's out, it's not smaller enough compared to a pico+doggy and not as adaptable (battery for one) so I'd just use the Pico. And, once anything passed that size point I might as well use the db or the legend and have 2+ days battery life.
